Hi!

I was asked to post this here:
Is the byte order in /proc/bus/usb/BBB/DDD platform dependant? I.e. is
there a bug in usbutils or in usbfs?

Reason for asking is that usbutils gives different results on PC and PPC
platforms.

I've tried usbutils-0.9-7 that comes with YDL 3.0 and I've tried
usbutils-0.11-1 built from a redhat src. Both seem to display the device
and product IDs backward on PowerPC:
idVendor 0x0204
idProduct 0x2156

On PC hardware, lsusb displays them in the correct order and also
identifies the device (this found on google):
idVendor 0x0402 ALi Corp.
idProduct 0x5621

Interesting enough, using the -t option, lsusb on ppc displays:
`-Dev# 1 Vendor 0x0000 Product 0x0000
`-Dev# 2 Vendor 0x0402 Product 0x5621

As far as I can tell, the lsusb -v takes its info directly from
/proc/bus/usb/NNN/NNN:
vid = buf[8] | (buf[9] << 8);
pid = buf[10] | (buf[11] << 8);
whereas lsusb -t takes it from /proc/bus/usb/devices.

I'm using kernel 2.4.26 from kernels.org on a Mac with YDL 3.0.1.

Thank you for your attention,
/Micke
