Hi,
I am running linux-next 20141208 on a imx51-babbage board and the
following hang is observed:
[1.243660] usbcore: registered new interface driver usb-storage
[1.261619] ci_hdrc ci_hdrc.1: doesn't support gadget
[1.266730] ci_hdrc ci_hdrc.1: EHCI Host Controller
[1.272058] ci_h
This makes us sure that all requests are completed before we unbind
gadget. There are assumptions in gadget API that all requests have to
be completed and leak of complete can break some usb function drivers.
For example unbind of ECM function can cause NULL pointer dereference:

With systemd 217, systemd-udevd complains every ~10 seconds (see below).
No error shows up on 216. The systemd people claim this is a drivers issue.

On i.MX6Q, the USBMISC registers are clocked by the IPG clock,
so there is no need to enable USBOH3 for the USBMISC driver.

Hi,
I have an Apricorn USB 3 disk dongle thing that claims to support UAS.
However, the kernel crashes when I plug it in[1].
I'm not sure what this is caused by, but I also have an ASMedia 2105 SATA
bridge that works with UAS just fine. Not sure if the Apricorn thing is simply
broken, or if this

yes, please ignore my ptp-gadget question. it was naive of me. the
developer (denx) had stated this posting request in his readme file,
and I simply followed it without thinking. it's probably abandoned
code by now.
is there a common ptp gadget client (for common embedded linux gadget
devices)

Access the registers at usbmisc needs the same clock with chipidea core,
both are usboh3.
