Hi,
Since I could not find solution on the net to switch USB bluetooth
device Sitecom CN-524 (aka Cambridge Silicon Radio CN-524;
idVendor=0a12, idProduct=100b) from HID to HCI mode, I made patch
myself after sniffing USB messages that Windows driver sends.
Since I'm not expert in programming, nor USB or bluetooth, the code
maybe imperfect. I'm sending anyway so someone could
review/adapt/improve and maybe even include in newer release.
My capture of Windows sending the switch is available on request...
