Hi !
On an embedded target I have to use the SL 811 HS (sigh!).
The driver is using sl_811_rh.c, this is basically a "root-hub in software". Now, since some time I have the following error and don't know why:
Which version of that driver are you using? As I understand, the the version that's been in the tree longest didn't work very well.
# modprobe hc_sl811 usb.c: registered new driver usbdevfs usb.c: registered new driver hub usb.c: new USB bus registered, assigned bus number 1 hub.c: USB hub found hub.c: 1 port detected hub.c: new USB device sl811-1, assigned address 2 usb_control/bulk_msg: timeout usb.c: USB device not accepting new address=2 (error=-110) hub.c: new USB device sl811-1, assigned address 3 usb_control/bulk_msg: timeout usb.c: USB device not accepting new address=3 (error=-110) rmmod hc_sl811 usb.c: USB disconnect on device sl811-0 address 1 Pattern test failed!! value = 0x0, s/b 0x42 usb.c: USB bus 1 deregistered
You said there was no device connected -- so the root hub had no business trying to assign any addresses. It must have lied to the hub driver about port status. If there's no device there, of course any attempt to talk to it will time out ...
