I did the following patch: --- libhid.c.orig Sat Jul 8 00:31:34 2006 +++ libhid.c Sat Jul 8 00:34:38 2006 @@ -645,7 +645,7 @@ upsdebugx(2, "Waiting for notifications..."); /* needs libusb-0.1.8 to work => use ifdef and autoconf */ - if ((size = libusb_get_interrupt(udev, &buf[0], 20, 5000)) > -1) + if ((size = libusb_get_interrupt(udev, &buf[0], 8, 5000)) > -1) { dump_hex ("Notification", buf, size); but I can't interpret the result: instead of -22 error, I got usbdevfs: usb_submit_urb returned -6 so I gave up and switched to a brand new gentoo server with kernel 2.6. All seems to be working fine now. No dmesg stuff. Therefore, it definitely looks like a kernel 2.4 problem (and/or uhci driver). Anyway, in case you need further testing with the 2.4, please let me know what you need me to do.
