Hans, I can't see usb is finding attached usb stick in normal dmesg, however when I enabled debug lines in usb_debug.h and gave ufs:/dev/da0a on mountroot prompt I see the usb stick: http://pastebin.ca/2299375 Like: ugen0.2: <JetFlash> at usbus0 usb_probe_and_attach: iclass=8/6/80 iindex=0/0 umass0: <JetFlash Mass Storage Device, class 0/0, rev 2.00/1.00, addr 2> on usbus0 umass0: SCSI over Bulk-Only; quirks = 0x4100 ... da0 at umass-sim0 bus 0 scbus0 target 0 lun 0 da0: <JetFlash Transcend 8GB 8.07> Removable Direct Access SCSI-4 device da0: 40.000MB/s transfers da0: 7656MB (15679488 512 byte sectors: 255H 63S/T 976C) ... Please ignore lines starting with "------------" etc in log, I just added it to debug before discovering DPRINTFs in usb_debug.h. Any reason why it can't see the stick before? Is there any error I should check or fix? thanks, Ganbold On Thu, Dec 27, 2012 at 5:04 PM, Hans Petter Selasky <hselasky@c2i.net> wrote: > On Wednesday 26 December 2012 17:05:35 Ganbold Tsagaankhuu wrote: >> Just some information, >> >> Still nothing useful yet, but with the help of andrew@, ray@, gonzo@ >> and other arm guys kernel boots: >> >> https://github.com/tsgan/allwinner_a10/blob/master/dmesg_ehci.txt >> >> Tried usb/ehci glue code, no success yet, so maybe I will leave it now >> and try next SD/MMC :) >> > > Hi, > > It looks like number of ports is zero.
