Hello, I'm just working on a AU1x00 based board which has an on-chip OHCI controller.
I'd like to enable the u-boot USB support for my board and since the u-boot code is derived from the Linux one I hope my message is not OT. :) The problem is that the controller talks with the root hub but when it starts talking with the USB device (a USB stick) I get: ---------- New Device 1 ---------- usb_control_msg: request: 0x6, requesttype: 0x80 value 0x100 index 0x0 length 0x8 INFO: -*-*- submit_control_msg -*-*- DEBUG: -*-*- SUB URB:[ 0] dev: 0,ep: 0-I,type:CTRL,len:0/8 stat:0x80000000 DEBUG: -*-*- SUB URB:[ 0] dev: 0,ep: 0-I,type:CTRL,len:0/8 stat:0x80000000 DEBUG: -*-*- Interrupt: 45 frame: 0 DEBUG: USB Schedule overrun DEBUG: -*-*- Interrupt: 0 frame: 0 DEBUG: roothub.a: 02001202 POTPGT=2 NOCP NPS NDP=2 DEBUG: roothub.b: 00000000 PPCM=0000 DR=0000 DEBUG: roothub.status: 00000000 DEBUG: roothub.portstatus [0] = 0x00000100 PPS DEBUG: roothub.portstatus [1] = 0x00000103 PPS PES CCS DEBUG: -*-*- RET(ctlr) URB:[ 0] dev: 0,ep: 0-I,type:CTRL,len:0/8 stat:0x20 DEBUG: -*-*- Interrupt: 0 frame: 0 DEBUG: roothub.a: 02001202 POTPGT=2 NOCP NPS NDP=2 DEBUG: roothub.b: 00000000 PPCM=0000 DR=0000 DEBUG: roothub.status: 00000000 DEBUG: roothub.portstatus [0] = 0x00000100 PPS DEBUG: roothub.portstatus [1] = 0x00000103 PPS PES CCS DEBUG: -*-*- RET(ctlr) URB:[ 0] dev: 0,ep: 0-I,type:CTRL,len:0/8 stat:0x20 USB device not responding, giving up (status=20) usb_control_msg: request: 0x1, requesttype: 0x23 value 0x1 index 0x2 length 0x0 INFO: -*-*- submit_control_msg -*-*- DEBUG: -*-*- SUB URB:[ 0] dev: 1,ep: 0-O,type:CTRL,len:0/0 stat:0x80000000 DEBUG: -*-*- SUB(rh) URB:[ 0] dev: 1,ep: 0-O,type:CTRL,len:0/0 stat:0x80000000 INFO: Root-Hub: adr: 1 cmd(8): 00000123 0001 0002 0000 INFO: WR:portstatus[1] 0x1 DEBUG: roothub.a: 02001202 POTPGT=2 NOCP NPS NDP=2 DEBUG: roothub.b: 00000000 PPCM=0000 DR=0000 DEBUG: roothub.status: 00000000 DEBUG: roothub.portstatus [0] = 0x00000100 PPS DEBUG: roothub.portstatus [1] = 0x00000101 PPS CCS DEBUG: -*-*- RET(rh) URB:[ 0] dev: 1,ep: 0-O,type:CTRL,len:0/0 stat:0x0 2 USB Device(s) found scanning bus for storage devices... 0 Storage Device(s) found Maybe someone can suggest to me some useful tips in order to resolve my problem.
