#17716: ramips: dwc_otg causes 'reset high-speed USB device number X' after
kernel
bump to 3.14
--------------------------------------+----------------------------------
Reporter: braveheart_leo@… | Owner: developers
Type: defect | Status: new
Priority: normal | Milestone: Chaos Calmer (trunk)
Component: kernel | Version: Trunk
Keywords: ramis dwc_otg dwc2 reset |
--------------------------------------+----------------------------------
My Buffalo external drive used to play nicely with this router, an ASUS
RT-N13UB1, running CHAOS CALMER (Bleeding Edge, r42321) and Linux 3.10.49.
Since the upgrade to Linux 3.14.16 for ramips targets, this is no longer
the case.
Here is the relevant dmesg that shows this external drive is working
perfectly well under 3.10.49:

Because of the repeated resets the dwc_otg module initiates, the drive's
partition does not appear, as indicated in this line ''sdb: detected
capacity change from 320072933376 to 0''
Here are some relevant lsusb outputs under 3.10.49:

I read in the past changesets that a switch to using dwc2 module was made,
but then it was reverted because the module does not play well with usb 3g
dongles (r37563). Perhaps now the switch to dwc2 can be made?
If not, then there was a significant change in 3.14 that affected the
dwc_otg module, at least for this particular drive. Unfortunately, the log
doesn't tell much, nor does it provide any more info to troubleshooting
this issue.
