Hi, 1) Try to get debugging from USB instead of OHCI.
sysctl hw.usb.ohci.debug=0 sysctl hw.usb.debug=15 Retry. 2) Patch /sys/dev/usb/ugen.c Change all lines looking like the following, that are not in a function named "xxx_callback": sce->read_stall = 1; sce->write_stall = 1; Into: sce->read_stall = 0; sce->write_stall = 0; Recompile ugen an try again. My analysis so far: The USB device refuses a control transfer, possibly the clear-stall request: ohci_setup_standard_chain: addr=2 endpt=0 sumlen=8 speed=2 ohci_setup_standard_chain: nexttog=1; data before transfer: TD(0xc4d6b600) at 0x0b06d600: -TOG0 delay=7 ec=0 cc=15 cbp=0x13ceb210 next=0x0b06d700 be=0x13ceb217 TD(0xc4d6b700) at 0x0b06d700: -R-IN-TOG1 delay=1 ec=0 cc=15 cbp=0x00000000 next=0x00000000 be=0xffffffff _ohci_append_qh: 0xc4d6b680 to 0xc4071980 ohci_check_transfer: xfer=0xc4f61140 checking transfer ohci_non_isoc_done: xfer=0xc4f61140 pipe=0xc4ee81b0 transfer done TD(0xc4d6b600) at 0x0b06d600: -TOG1 delay=7 ec=0 cc=0 cbp=0x00000000 next=0x00000000 be=0x13ceb217 ohci_device_done: xfer=0xc4f61140, pipe=0xc4ee81b0, error=22 The OHCI wants to receive 4 bytes from endpoint 1, but does never get those bytes.
