Hello, I've recently buy a new TFT screen : Dell UltraSharp 1704FPT which have a USB Hub (4 ports) in it (http://accessories.us.dell.com/sna/ProductDetail.aspx?sku=320-3952&c=us&l=en&cs=19&category_id=210&first=true&page=productlisting.aspx).
When I plug USB between the screen and my motherboard. I get theses messages in dmesg (with USB debug) with 2.6.11.9: [c15c5240] link (015c51b2) element (015c4040) 0: [c15c4040] link (015c4080) e0 Stalled CRC/Timeo Length=7 MaxLen=7 DT0 EndPt=0 Dev=0, PID=2d(SETUP) (buf=01a938a0) 1: [c15c4080] link (015c40c0) e3 SPD Active Length=0 MaxLen=3f DT1 EndPt=0 Dev=0, PID=69(IN) (buf=009bc1e0) 2: [c15c40c0] link (00000001) e3 IOC Active Length=0 MaxLen=7ff DT1 EndPt=0 Dev=0, PID=e1(OUT) (buf=00000000) usb 2-1: device descriptor read/64, error -71 uhci_hcd 0000:00:09.0: uhci_result_control: failed with status 440000 [c15c5240] link (015c51b2) element (015c4040) 0: [c15c4040] link (015c4080) e0 Stalled CRC/Timeo Length=7 MaxLen=7 DT0 EndPt=0 Dev=0, PID=2d(SETUP) (buf=1893c6c0) 1: [c15c4080] link (015c40c0) e3 SPD Active Length=0 MaxLen=3f DT1 EndPt=0 Dev=0, PID=69(IN) (buf=009bc1e0) 2: [c15c40c0] link (00000001) e3 IOC Active Length=0 MaxLen=7ff DT1 EndPt=0 Dev=0, PID=e1(OUT) (buf=00000000) usb 2-1: device descriptor read/64, error -71 usb 2-1: new full speed USB device using uhci_hcd and address 7 uhci_hcd 0000:00:09.0: uhci_result_control: failed with status 440000 [c15c5240] link (015c51b2) element (015c4040) 0: [c15c4040] link (015c4080) e0 Stalled CRC/Timeo Length=7 MaxLen=7 DT0 EndPt=0 Dev=0, PID=2d(SETUP) (buf=16583340) 1: [c15c4080] link (015c40c0) e3 SPD Active Length=0 MaxLen=3f DT1 EndPt=0 Dev=0, PID=69(IN) (buf=009bc1e0) 2: [c15c40c0] link (00000001) e3 IOC Active Length=0 MaxLen=7ff DT1 EndPt=0 Dev=0, PID=e1(OUT) (buf=00000000) usb 2-1: device descriptor read/64, error -71 uhci_hcd 0000:00:09.0: uhci_result_control: failed with status 440000 [c15c5240] link (015c51b2) element (015c4040) 0: [c15c4040] link (015c4080) e0 Stalled CRC/Timeo Length=7 MaxLen=7 DT0 EndPt=0 Dev=0, PID=2d(SETUP) (buf=165838e0) 1: [c15c4080] link (015c40c0) e3 SPD Active Length=0 MaxLen=3f DT1 EndPt=0 Dev=0, PID=69(IN) (buf=009bc1e0) 2: [c15c40c0] link (00000001) e3 IOC Active Length=0 MaxLen=7ff DT1 EndPt=0 Dev=0, PID=e1(OUT) (buf=00000000) usb 2-1: device descriptor read/64, error -71 hub 2-0:1.0: state 5 ports 2 chg 0000 evt 0002 I've made a lot of search on google about theses errors and didn't find anything. I've include my .config in attachment. I _think_ it's not a configuration problem but maybe a kernel one or a hardware one. I don't have Windows to test it so :/ What can I do for that ? I know C code (never made a kernel hack). Thanks Beber
