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.
