Greetings all, I have a set of seven ftdi_sio devices connected to a seven-port USB hub (actually I have several hubs connected, one of which is giving me this problem). When I plug the hub into the machine with all devices connected to the hub, the lights on the hub corresponding to each of the ports start to light up, one-by-one. In the past, all the lights would turn on and everything worked properly; however, lately a few of the lights will turn on, then all lights turn off, and this repeats indefinitely. I've include a copy of a sample of the logs that are generated when this occurs.
The devices I'm working with are full-speed devices, so I'm not using EHCI at all. Anyone have any idea what might be causing this? If you need any additional information, please let me know. Thanks, Andy $ cat /proc/version Linux version 2.6.17-gentoo-r8 ([EMAIL PROTECTED]) (gcc version 3.4.6 (Gentoo 3.4.6-r1, ssp-3.4.5-1.0, pie-8.7.9)) #2 SMP Tue Dec 19 20:37:38 EST 2006 $ cat sample_log hub 5-2:1.0: cannot reset port 2 (err = -71) hub 5-2:1.0: port 2 not enabled, trying reset again... uhci_hcd 0000:00:1d.2: uhci_result_control: failed with status 440000 [f7df7380] link (37df7302) element (353f5150) urb_priv [f58d63d8] urb [f5c715c0] qh [f7df7380] Dev=42 EP=0(OUT) CTL FSBR 1: [f53f5150] link (353f5090) e0 Stalled CRC/Timeo Length=7 MaxLen=7 DT0 EndPt=0 Dev=2a, PID=2d(SETUP) (buf=37596aa0) 2: [f53f5090] link (353f5180) e3 IOC Active Length=0 MaxLen=7ff DT1 EndPt=0 Dev=2a, PID=69(IN) (buf=00000000) Dummy TD [f53f5180] link (353f5090) e0 Length=0 MaxLen=7ff DT0 EndPt=0 Dev=0, PID=e1(OUT) (buf=00000000) hub 5-2:1.0: cannot reset port 2 (err = -71) hub 5-2:1.0: port 2 not enabled, trying reset again... hub 5-2:1.0: ev=2a, PID=2d(SETUP) (buf=37596aa0) 2: [f53f5090] link (353f5120) e3 SPD Active Length=0 MaxLen=3 DT1 EndPt=0 Dev=2a, PID=69(IN) (buf=353e2a20) 3: [f53f5120] link (353f51e0) e3 IOC Active Length=0 MaxLen=7ff DT1 EndPt=0 Dev=2a, PID=e1(OUT) (buf=00000000) Dummy TD [f53f51e0] link (353f5090) e0 Length=0 MaxLen=7ff DT0 EndPt=0 Dev=0, PID=e1(OUT) (buf=00000000) hub 5-2:1.0: hub_port_status failed (err = -71) uhci_hcd 0000:00:1d.2: uhci_result_control: failed with status 440000 [f7df7380] link (37df7302) element (353f51e0) urb_priv [f58d6918] urb [f5c715c0] qh [f7df7380] Dev=42 EP=0(IN) CTL FSBR 1: [f53f51e0] link (353f50f0) e0 Stalled CRC/Timeo Length=7 MaxLen=7 DT0 EndPt=0 Dev=2a, PID=2d(SETUP) (buf=37596aa0) 2: [f53f50f0] link (353f5150) e3 SPD Active Length=0 MaxLen=3 DT1 EndPt=0 Dev=2a, PID=69(IN) (buf=353e2a20) 3: [f53f5150] link (353f5180) e3 IOC Active Length=0 MaxLen=7ff DT1 EndPt=0 Dev=2a, PID=e1(OUT) (buf=00000000) Dummy TD [f53f5180] link (353f51b0) e0 Length=0 MaxLen=7ff DT0 EndPt=0 Dev=0, PID=e1(OUT) (buf=00000000) hub 5-2:1.0: hub_port_status failed (err = -71) uhci_hcd 0000:00:1d.2: uhci_result_control: failed with status 440000 [f7df7380] link (37df7302) element (353f5180) urb_priv [f59f2b64] urb [f5c715c0] qh [f7df7380] Dev=42 EP=0(IN) CTL FSBR 1: [f53f5180] link (353f5090) e0 Stalled CRC/Timeo Length=7 MaxLen=7 DT0 EndPt=0 Dev=2a, PID=2d(SETUP) (buf=37596aa0) 2: [f53f5090] link (353f5120) e3 SPD Active Length=0 MaxLen=3 DT1 EndPt=0 Dev=2a, PID=69(IN) (buf=353e2a20) 3: [f53f5120] link (353f51b0) e3 IOC Active Length=0 MaxLen=7ff DT1 EndPt=0 Dev=2a, PID=e1(OUT) (buf=00000000) Dummy TD [f53f51b0] link (353f5090) e0 Length=0 MaxLen=7ff DT0 EndPt=0 Dev=0, PID=e1(OUT) (buf=00000000) hub 5-2:1.0: hub_port_status failed (err = -71) uhci_hcd 0000:00:1d.2: uhci_result_control: failed with status 440000 [f7df7380] link (37df7302) element (353f51b0) urb_priv [f58d68a8] imeo Length=7 MaxLen=7 DT0 EndPt=0 Dev=30, PID=2d(SETUP) (buf=37596c00) 2: [f53f5090] link (353f50f0) e3 SPD Active Length=0 MaxLen=3 DT1 EndPt=0 Dev=30, PID=69(IN) (buf=353c17e0) 3: [f53f50f0] link (353f51e0) e3 IOC Active Length=0 MaxLen=7ff DT1 EndPt=0 Dev=30, PID=e1(OUT) (buf=00000000) Dummy TD [f53f51e0] link (353f5090) e0 Length=0 MaxLen=7ff DT0 EndPt=0 Dev=0, PID=e1(OUT) (buf=00000000) ------------------------------------------------------------------------- Take Surveys.
