Hi, since kernel 3.1 I cannot really use my HP USB printer anymore. Every try to print more than one page results in a USB reset disconnecting the USB I/O: Mar 6 18:37:42 Hygiea kernel: [45838.854035] usb 1-4: reset high speed USB device number 5 using ehci_hcd Mar 6 18:37:42 Hygiea hp[21391]: io/hpmud/musb.c 1043: bulk_write failed buf=0x7fff7b5aed40 size=8192 len=-34: Success Mar 6 18:37:42 Hygiea hp[21391]: io/hpmud/musb.c 1423: unable to write data hp:/usb/Officejet_6300_series?serial=CN69DCH2GW04M4: Success Mar 6 18:37:42 Hygiea kernel: [45838.969179] Did not find alt setting 1 for intf 0, config 1 Mar 6 18:37:42 Hygiea kernel: [45838.969189] usb 1-4: usbfs: process 21391 (hp) did not claim interface 1 before use I first noticed when I updated to openSUSE 12.1 which has kernel 3.1 (and recently 3.1.9) and therefore reported it also there: https://bugzilla.novell.com/show_bug.cgi?id=751712 I've also just tried version 3.2.9 (I think there is no newer official release yet?) which shows the same issue. I was trying to bisect from git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git (I'll attach the bisect log file as well) and it pointed to " fcda12e7f6d58d61997681a9d41779e3fd2ffc94 is the first bad commit " But for me that merge is not obviously related so I'm pretty lost. (I'm not a kernel developer anyway) Thanks, Wolfgang
