Hi, I have a few weird USB related errors. Hardware: beagleboard rev C2. OS: 2.6.28 (angstrom, r15 version) If I connect my pvrusb2 controller directly to the usb host port the device works as expected. However if I connect the device through a (powered) usb hub, the device does not work. dmesg says: usb 1-2.2: new high speed USB device using ehci-omap and address 5 usb 1-2.2: configuration #1 chosen from 1 choice usb 1-2.2: firmware: requesting v4l-pvrusb2-29xxx-01.fw pvrusb2: Device microcontroller firmware (re)loaded; it should now reset and reconnect. but it does not reconnect. I would not expect a usb hub to have such an effect. Note that the hub is working and that devices like an ethernet dongle and a bluetooth dongle work like a charm with the hub. I also saw a fw load problem with the hardware (same system). At that point dmesg said: usb 1-2.2: new high speed USB device using ehci-omap and address 4 usb 1-2.2: configuration #1 chosen from 1 choice Linux video capture interface: v2.00 usbcore: registered new interface driver pvrusb2 pvrusb2: V4L in-tree version:Hauppauge WinTV-PVR-USB2 MPEG2 Encoder/Tuner pvrusb2: Debug mask is 31 (0x1f) usb 1-2.2: firmware: requesting v4l-pvrusb2-29xxx-01.fw pvrusb2: ***WARNING*** Device fx2 controller firmware seems to be missing. pvrusb2: Did you install the pvrusb2 firmware files in their proper location? pvrusb2: request_firmware unable to locate fx2 controller file v4l-pvrusb2-29xxx-01.fw pvrusb2: Failure uploading firmware1 pvrusb2: Device initialization was not successful. pvrusb2: Giving up since device microcontroller firmware appears to be missing. If I then unplug and replug I get the first message (about reset and reconnect). The other problem I have is with my wireless zd1211 based wifi dongle. If I connect it I get: usb 1-2.2: new high speed USB device using ehci-omap and address 6 usb 1-2.2: configuration #1 chosen from 1 choice usb 1-2.2: reset high speed USB device using ehci-omap and address 6 phy0: Selected rate control algorithm 'pid' zd1211rw 1-2.2:1.0: phy0 usb 1-2.2: firmware: requesting zd1211/zd1211_ub usb 1-2.2: firmware: requesting zd1211/zd1211_uphr usb 1-2.2: Could not load firmware file zd1211/zd1211_uphr. Error number -2 zd1211rw 1-2.2:1.0: couldn't load firmware. Error number -2 Whether the dongle is directly connected or through a hub does not make a dfifference However the firmware is there and the very same firmware works under opensuse and used to work under 2.6.27 Anyone an idea ?
