Trick for a cheap bluetooth dongle
Last week I bought a cheap bluetooth dongle for my home desktop. My wife just wants to copy MP3 to her cellphone, and download pictures from the phone to the computer, so I didn’t see the need to spend too much. So I got this weird dongle that simply identifies itself as ES-388 on the box. When I got home, connected, and:
hcid: Can’t read name for hci0: Input/output error (5)
hcid: Can’t read class of device on hci0: Input/output error(5)
Dam… After googling around looking for the product name (found nothing) and the USB ID (0a5c:2100 Broadcom Corp.), I finally discovered that this little guy is, in fact, a Broadcom 2045 (why hide?). After some more google love, I finally stumbled with the final tip that fixed my problems:
options hci_usb reset=1
Add the above line to /etc/modprobe.conf and be happy. Now I can transfer files back and forth, easily (well, not that much), even though veeeeery slow.🙂
Oh, before you ask, the phone is a Sony Z550i.
