Final note: I bought one of those Belkin NEC-based USB 2.0 PCI
controllers from Wal-Mart and plopped it in the KT333 machine. The USB
2.0 drive then worked perfectly:
12.1 MB/s write sustained at 7% CPU (bonnie++)
15.1 MB/s read sustained at 4% CPU (bonnie++)
No errors whatsoever. Very good.

I just try
As a follow-up to the bug report below, I returned the USB Caddy and got
a new one based on the ALI chipset. I also did some more testing. As
Ged Haywood pointed out to me, this seems to be a problem with the VIA
host controller driver and not the USB->IDE caddy itself as the same
problems occur

Hi,
I bought a Creative Audigy2 NX USB sound card. It is nice and works
perfectly (under Win) but I can get it to work under linux (kernel 2.4 and
2.6). It is very annoying, I have to use win just for it, I like music
while I do everything...
Do you think I have any chance to see it working under

Dear Sir,
I am a Linux developer. My application code reads sectors from an USB
floppy.
While testing this code, I noticed that if I start the application and after
doing some read calls if I remove the cable of USB floppy from the drive,
then read system call never returns. When I take "ps -efl"

Hello,
i am testing my USB interface logic code modelled in vhdl for version
1.1. I need help on how to generate test data for testing the interface. i
have tested the enumeration type of transfer by using a linux pc as usb
host, but i find the data on the bus to be quite unreliable, i mean i have
Hi folks,
I'm using an external IDE drive thru an USB1 link, which works well in terms
of data integrity. Since it's USB1, the transfer rates are quite poor (<1MB/sec),
but my problem is that when I transfer big files (big enough to last more than a few
seconds), the CPU consumption becomes incr

Hi!
I have a very similar problem with a new variant of the Logitech Internet
Navigator keyboard and Linux 2.6.x. About half of this keyboard's special
keys work, the other half
