USB 2.0 vs USB 3.0Recently; i found myself over at Best Buy and Found a Toshiba Hard Drive,=
=20
1 Tb for $99 and i thought; 'That is too good to be true.'
and also; Toshiba ??? Would they betray me ?
So i bought it.
And i did get it to work a little bit, which would suggest that the USB 3.0=
cable that came with it, Would work with my MacBook and its USB 2.0 Vulvas=
,=20
but it didn't work very well. The Plug was 'Wiggly' And the Cable that came=
with it was like 4 inches long, and it is Very Difficult to find an Extens=
ion Cable for this sort of thing. i wanted to just drop by a store and get =
one, but i had to buy one on the Interweb, from Amazon, and the Shortest th=
ey had was for 276 Feet.=20
Or so.
Also; This Wiggliness that i spoke of, The HardDrive wouldn't 'Connect' Pro=
perly, and by this, i mean that the little light on the Hard Drive would no=
t come on, Unless i pressed down ( Gently ) on the USB 3.0 Plug.=20
All i wanted was a slightly longer cable.
So the Plug for it was Wiggly Too!
And the Hard Drive did not work well,=20
i wanted to Partition it, because i had heard or read that i had to partiti=
on it to get it to load The Start Up Disk and Then Re-Boot my MacBook from =
it, Which i now suspect, may not be correct ( ? )
But anyways; While trying to Partition the Hard Drive, it somehow Broke.
i seemed to have done it once, then when i decided to eliminate one of the =

USB 3.0 Hub treatment of USB 2.0 connections.
My old USB 2.0 hub (7 port with external power) had been getting
increasingly flaky over time with various devices dropping out and
re-connecting (printer, keyboard wireless receiver and so on) so I
bought a new one. An Anker 7 port USB 3.0 with ext. p/s.
I had no USB 3.0 peripherals when I first hooked it up.
When looking at system profiler there were no USB 3.0 devices - not even
the hub - showing. Fastest interface was shown as 480 Mb/s.
Today I received a couple USB 3.0 docks and after initially hooking them
straight to the Mac, I tried, as an experiment, passing the USB 3.0
through the hub.
Did not connect.
So I powered off the hub and disconnected it from the Mac, then
reconnected it all.
The disk appeared. And the Highspeed USB 3.0 appeared in profile (at 5
Gb/s).
So once it's running with USB 2.0 devices only connected, the hub
doesn't take to new 3.0 devices showing up. Once they're there, it's
fine. Copy rate via the hub from the disk on the 3.0 was the same as a
direct connection. (I've since put the USB 3.0 disk directly to the
computer).
I had assumed that USB 2.0 traffic would be "wrapped" in USB 3.0 and
passed to the computer and unwrapped. But it appears it remains
electrically and logically USB 2.0. (Then I found this:

USB 2.0 problem: Could USB stick have been the cause?I recently had my T41's (2373-3kg) mother board replaced (on warranty)
because of the problem described on the following page:
http://www.thinkwiki.org/wiki/Problem_with_USB_2.0
In short: My USB 2.0 ports stopped working properly under LINUX and
under Windows.
Now, I wonder whether the cause of the problem could be the following
unorthodox USB memory stick. It was the last new USB device that I
bought before the problem started to occur.

move ZFS mountpoint from USB 1.1 to USB 2.0 portI created a mountpoint called /tdusb1 on a USB 1.1 port conncted to a
1TB LaCie hard drive. I discoverd that our system has a USB 2.0 port
and want to move the logical mountpoint to a new physical USB port.
How do I do it?
Actually, I will need to do the same sort of thing from one Solaris 10
system to another in the future. I don't care about plug-and-play and
hot swappable as long as I can read the same drive from different Sun
systems.
I assume that there are ZFS related commands for doing this but don't
want to experiment too much as the USB hard drive already has valuable

USB flash drive speed USB1.1 vs USB 2.0My laptop's USB ports advertised to be USB 2.0
When I use one of them to transfer a 106 MegaByte folder of many subfolders
and files to a Sandisk 256 MB flash drive it takes about fourty minutes 2.7
MegaBytes per Minute. Does this sound right for USB 2.0 or USB 1.1? The
new laptop is not executing any other programs and the hard disk light is
off.
Big education for me. USB 1.1 and 2.0 are standards,
not speeds. Each has a high speed and a low speed. To know what your
peripheral is going to do you must ignore the 1.1 and 2.0 designations as
meaningless. What counts is ...
laptop usb 1.1 + scanner usb 2.0 + modem ADSL = ?????!!!!!*****I have a laptop with a single USB 1.1 port. My new scanner (Epson 3170 usb

together. I have tried to make them "cooperate" with a Sitecom Usb pocket
hub which needs an external power adapter and of course it doesn't work
without it; do you think it would work if I had one? Or is there any other
possibility (Pcmcia/usb card for example)? Thank you for your future wise
advice.
Good chance powered hub will work, but not guaranteed.

I have successfully synched using this pilot / cradle / PC

I have just run the gnome pilot configuration applet.
I have a USB cradle and have tried various dev/pilot settings.
When I press the HotSync button on the cradle - no application in
Linux responds.
I DO see the messages below in dmesg - so some activity is certainly
going on - but have I missed a step to get the sync to write any thing

What operating system are you using? You need USB 2.0 drivers as
wellas the hardware. Are you sure you have the correct drivers
installed for the new USB card? If you have Windows XP, it's probably
already done. On something older like Windows 98, could be more
difficult.

USB Portable 3.0/2.0 reliabilityI need a 1TB or larger portable hard drive for use in 3 world foreign
net cafes.
The idea of NOT needing a separate power supply appeals to me, but I
wonder if the portable USB drives are less reliable than using an
internal drive with a usb adapter and separate power supply? Also you
have heat problems with these portable drives that are less of a
problem with a bare internal drive I am thinking.
What factors govern this? How do the newer usb 3.0 portable drives
compare to the earlier ones? Most of the reviews on these portable usb
drives are pretty dismal-lots of complain...
old USB cables how 2 tell from 2.0?Well I have an assortment of older USB (1.0 & 1.1) cables probably came
with older USB devices.
I finally got some newer USB 2.0 devices. I got newer 5th gen iPod
(only syncs with USB 2.0) I did install a PCI USB 2.0 card in an older
G4 & G4 iMac does have USB 2.0.
Are USB 2.0 cables special (are older ones NOT useable on 2.0 devices?)
How do I tell the difference? Is there any easy way? I have some I am
not sure about their vintage.
Thanks for comments.

Toshiba Satellite 2410-S185 / PS241U-851457 is NOT USB 2.0 as advertised. It is only USB 1.1I purchased a Toshiba laptop 2410-S185 from CDW almost a year ago
The system specs claimed to support USB 2.0.
This didn�t seem to be the case when I tried to get it working.
I eventually looked up the Intel Chipset at Intel�s website and found
it DOES NOT support 2.0 (Intel Chipset 82801CA)
I spent 4 hours on the phone with Toshiba before I was upgraded to a
lvel two tech and convinced them of the problem.
They told me �Thank you for letting us know the error in our
documentation, I�ll have someone fix that for you�
Of course there is NO WAY they�re going to get off the hook that easy.
I can�t imagine how many of these they sold with such a major mistake.
I have a feeling they�re just going to send me a usb2.0 pccard
adapter. They BETTER do at least that much.
I'd say it qualifies for a class action law suit.
Not that I myself have the energy or motivation to take it that far.

New Printer with USB 2.0 - Old PC with USB 1.1 PortsI am FINALLY getting around to getting a new printer - but I have a 4
year old laptop that has two USB 1.1 ports. Will a new printer with a
USB 2.0 connection work with my laptop? I heard it will - but will be
slower than designed to be. I am planning on getting another HP
OfficeJet (my old one lasted 7 years!!!!).
Also, can I use a regular USB 1.1 cable? Is there a difference between
USB cables (2.0 different than 1.1?).
Thanks!

external 2.5" USB 2.0 enclosure
Hi group,
I have seen an a powerless USB 2.0 enclosure at a local computer store
that uses two USB ports on the PC and does not require an external power
source. But I don't remember the brand. Can someone recommend a
brand/model? Does anyone know if all the powerless USB 2.0 enclosures
require two USB ports?
/sn
I have a USB powered enclosure (that also takes a 6v adaptor if for whatever
reason the USB port is not supplying enough juice) that requires only one
USB port to power itself. I have a 20GB drive housed in it and have had no
problems at all over the last 5 months. I bought it for $49 Cdn. online and
am happy with it. It's a "GoGoDrive Firewire/USB 2.0 enclosure" TT945
series. I got it from mycableshop.com.
Hope this helps,
