(I can't seem to get to the usbutils site right now to see if there's a separate list for user-space USB programs, so please excuse me if this is not the right list.)
While writing USB firmware for the PIC16C765, I noticed that lsusb can't read the string descriptors from even the stock Microchip firmware. This seems to be limited to lsusb, as the strings show up in /proc/bus/usb/devices and in the HID driver's initialization message. Here's the output of 'lsusb' run as root (ignore the bogus VID/PID-- just testing another set of HID descriptors): [...] Bus 001 Device 003: ID 04b4:0316 Cypress Semiconductor Language IDs: none (invalid length string descriptor bf; len=0) string descriptor 1 invalid (bf bf; len=0) string descriptor 2 invalid (bf bf; len=0) string descriptor 3 invalid (bf bf; len=0) [...] Language IDs: none (invalid length string descriptor bf; len=0) This particular message came from usbutils-0.9, and also appears in the output of 'lsusb -v' in 0.11. The kernel is 2.4.18-19.8.0 (an update from RedHat 8.0), and I am using the 'uhci' HCD (not usb-uhci). The only kernel message is "usbdevfs: process 11685 (lsusb) did not claim interface 0 before use". My first guess that this is not affecting the retrieval of the string descriptors, since the string descriptors listed above are present in the device descriptor (and not at the interface level). Any ideas? Pointers to a usbutils-specific mailing list?
