I found a regression in the lantiq xway USB driver.
In BB 14.07 everything worked fine.
In CC 15.05 (and rc2/3) the problem occures.
The connected devices (except hubs) are resetted over and over again. Only
mass storage devices are tested. The devices are excessively resetted, so
the SCSI subsystem reports 0 drive capacity.
The router is a Buffalo WBMR-HP-G300-H.
Tested BB 14.07 final and CC 15.05-rc2/3 and CC 15.05 final.
Installed software via opkg:
- kmod-usb2
- kmod-usb-storage
- kmod-usb-storage-extras
- kmod-fs-ext4
- kmod-scsi-core
- block-mount
- usbutils
Attached logs:
- dmesg of BB 14.07
- dmesg of CC 15.05
both taken right after connecting the device
It also happens to thumb drives (extroot is now impossible).
I also found another thread in the forum:
[https://forum.openwrt.org/viewtopic.php?id=60057]
In the thread it is dumbed down to an USB power issue.
In my case it is not a power issue, since the drive has its own PSU.
