So today when I attached my wireless keyboard I discovered that other Bluetooth USB adapter (which I used to connect with my headphones, receive files from phone) is not working anymore.
When I type
lsusb in Terminal I get only one busy spot.
Bus 004 Device 004: ID 046d:c534 Logitech, Inc. Unifying Receiver which is the receiver for keyboard and mouse.
All others are like this
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Is there a way to get them both working or make the old one to accept keyboard and mouse also, because I think the receiver doesn't have functionality for all this (file transfer, headphones etc.)?
P.S. - I am using Ubuntu 16.04 LTS 32-bit
