New Printer with USB 2.0 - Old PC with USB 1.1 Ports
I 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?).

is there a chip, in functionality like a FT245BM for USB 2.0 ?
I found on websites mentioning the FT245BM compatible for USB 2.0,
but i think they don't use USB 2.0, because transfer rate is "only" 1
MByte/s, which looks like high speed USB.
Is there a faster parallel USB chip, which achieves more than 1 MByte / s ?
I think with USB 2.0 there must be at least a factor of 10 to this speed ?

Control Panel -> System -> Hardware -> Device Manager.
Then right click on the USB hub(s) and click Properties.
Another way is to plug in a known USB 2.0 device into
the port. The system will pop a warning if the port is

plug something into it that runs on USB 2.0. You'll get an error message.

Connectors for USB are the same for USB 1.1 or 2. Win2K does not support
USB2 unless an MS patch is applied
The link will answer your question. Even with the patch, it is up to
the vendor to supply a Win2K compatible driver for USB2. Check that the
USB device is in fact compatible.

...Can not boot once USB 2.0 external hard drive installed on Windows XP
I installed an external Western Digital in an external USB 2.0 case to
my Compaq computer yesterday. The hard drive (once formatted) works
fine once I plug it into the system and I can use it as an extra drive
which is great.
However if I "REBOOT" the Windows XP machine, it hangs after memory
test and will not continue to boot. If I unplug or poweroff the

raw data such as analog to digital conversion, down-conversion and
