Hi Greg,
Is there any way to access port information from within the Kernel
module?
I want to access whatever the information in /proc/bus/usb/devices, but
within my driver module.
Regards,
Nagan,

The problem I'm having is that I can’t find 40G usb external harddisk in
linux. BUT it can find 128m u disk. Why? Can you help me? Thanks
When I use u disk, everything is ok. I can mount and use the u disk.
When I changed into mobile harddisk, I can’t mount it. Both of the
mobile harddisk and u di

Speaking of control timeouts, I know someone with a similar problem.
Check this out:

Tom,
Thanks for your response. Just to make sure of my ALSA drivers, I
installed and rebuilt the latest ALSA 1.0.8 release. Much to my chagrin,
(and happyness), the Byterunner WORKS now for recording/playback!!! (I
don't personally need the extra playback channel functionality)
Thanks for t

Hello,
I have written a Linux USB driver for a development board I have. It
has 2 interrupt endpoints, one in and one out. The driver does
nothing more than recieves a packet from the board, displays the
contents (with a printk), and transmits the same packet to the board.
