Hello
I am currently trying to troubleshoot my Arduino setup, which consists of a bluetooth receiver plugged into an knock off USB 2.0 shield on an Arduino Uno. Everything was working as intended until just now, with the ability for me to connect devices to the receiver and test their function. However, between then and testing some separate sketch on the Arduino the dongle stopped working, and it doesn't look like the receiver is being powered. I have confirmed this by running the QC example sketch and having it stall at the 'Checking USB device communication' step. Plugging in a USB keyboard into the same spot passes the test immediately, and an old xbox 360 controller as well. When plugging in the bluetooth receiver into my computer, it works as it originally did, so it seems only on the Arduino does it fail to function.
I have come across a similar post that has since been locked, however no answer was provided:
Thank you!
