I have noticed some inconsistencies in usb-device-handling. My main Problem (0) was: if I connect my usb-scanner "HP ScanJet 4300C" (officially listed in uscanner(4) as supported device), it is recognized as known device, but usbd fails to attach it with the following message (kernel option USB_DEBUG is set): usbd_new_device bus=0xc25e1000 port=1 depth=1 speed=2 usbd_new_device: adding unig addr=2, rev=100, class=0, subclass=0, protocol=0, maxpacket=8, len=18, speed=2 usbd_new_device: new dev (addr 2), dev=0xc286c480, parent=0xc259bb80 //value of devinfo after calling usbd_devinfo(dev,1,devinfo) is: //"Hewlett Packard Scanjet 4300C, class 0/0, rev 1.00/0.00, addr 2" usbd_probe_and_attach: no device specific driver found usbd_probe_and_attach: looping over 1 configurations uhub0: port 1, set config at addr 2 failed, error=STALLED usbd_remove_device: 0xc286c480 uhub_explore: usb_new_device failed, error=STALLED uhub0: device problem (STALLED), disabling port 1 ------------- 1)I have compiled my usb_subr.c with -DUSBVERBOSE set and there were some more problems to review: CHICONY2 and AIPTEK2 vendors were not declared! ------------- 2)And the last one: as I plugged my "Olympus C-350" digital camera, it caused a kernel panic (page fault while in kernel mode, code = "supervisor read, page not present"). If the camera is plugged in before the start, system refuses to boot. ------------- Many people would be thankful if the problems would be fixed in the next version ;-) Best regards, Ivan Good >How-To-Repeat: 0)Ask the developer of the 4300C-interface to connect the scanner and try to work with it. 1)Try to compile /usr/src/sys/dev/usb/usb_subr.c with defined USBVERBOSE option. 2)Connect the C-350 Olympus camera. >Fix: No known fixes available. The problem seems to be rather old as I found many unanswered questions about it in several forums on the net. >Release-Note: >Audit-Trail: >Unformatted:
