Hello everyone,
I am developing a product with a Raspberry Pi in it, and we are using Wi-Pi dongles, which use the rt2800usb driver. I've written a program that manages the network. This program puts the WiFi stick in ad-hoc mode and automatically selects a channel based on what other Pi's select and how much background noise there is.
However, when the program changes the channel the Wi-Pi is on, it stops transmitting beacons frames, which means that other devices, such as iPads, can no longer see the network.
In addition, I see a lot of this in dmesg when I build rt2800usb with debugging enabled:

I am using Linux kernel version 3.6.11. If need be, we can use a different WiFi stick with a different driver, but I'd like to get this one working if possible.
