- <li><em>subject</em>: [ale] usbdevfs confusion</li>
The device is listed as 004 when I run "lsusb". When I look in
/proc/bus/usb/001/ I see the device listed as: 004. However, when I
try to open the device from my program: programname -d
/proc/bus/usb/001/004, it doesn't work.
I also tried creating a node in /dev for "ttyUSB0" (using mknod c 188
0), and that doesn't work either.
Is usbdevfs not meant to be accessed as a file device like /dev is?
Can anyone shed any light on this for me? I'm pretty confused here.
Thanks!
