Review of Linux Compatibility
The Delock 61889 Bluetooth USB stick has the USB ID 0a5c:21e8:
Bus 008 Device 002: ID 0a5c:21e8 Broadcom Corp. BCM20702A0 Bluetooth 4.0
and is automatically supported by latest Linux kernel versions thanks to the “btusb” kernel module.
BeiIf an older kernel version is used the USB ID of the Delock 61889 might be unknown to the kernel and therefore no driver is loaded. This can be corrected by modifying the file /etc/modprobe.d/medialink-btusb.conf
gksu gedit /etc/modprobe.d/medialink-btusb.conf
and adding the following line:
install usb:v0A5Cp21E8d*dc*dsc*dp*ic*isc*ip* /sbin/modprobe btusb; echo "0a5c 21e8" > /sys/bus/usb/drivers/btusb/new_id
The pairing with other bluetooth devices can be carried out by tools like “bluetoothctl”. The following command scans for other Bluetooth devices:
[NEW] Device **:**:**:**:**:** Philips SHB7000
The connection with the device can be established by entering the command
A USB stick with the same hardware is sold under the name “Medialink USB Bluetooth Adapter – Version 4.0″ and has the same Linux compatibility as the Delock 61778. This version of the sticks has a slightly different housing, at the front side the brand’s name “Medialink” imprinted.
