Hi guys, not sure if this issue I'm seeing is a know one or not. I
searched for similar bugs but haven't seen this.
I'll open a new bug if it is needed.
I'm using Carambola [1] device with Attitude Adjustment 12.09 which is
based upon Ralink chipset.
Usb bluetooth dongle gets disconnected every 4.5~6.5 minutes and then
gets new usb device number. Not it came up to device number 13.
When it disconnects then kernel log shows a bunch of:
dwc_otg: Device Not Supported
Hi,
can you try with an external powered hub ?

Hi,
From my past experience with the AR9331, can you try with both a
self-powered and bus-powered _high-speed_ (enumerated as such in the
logs) USB hub and/or with WiFi turned off?

Hi,
The log shows dwc_otg, so i am guessing he is on lantiq or ralink hardware.
however i do agree, that this smells like a usb power issue.

Hi John,
Yes, I know it is the RT350-based Carambola 1 and not the AR9331-based
Carambola 2 based, but I suggested these tests in order to determine if the
issues are related to the USB power or decoupling, to a compatibility problem
with full-speed devices or has something to do with WiFi.
