Hi all,
I recently purchased a class 1 "sweex" bluetooth USB dongle. It has a
broadcom bcm2035
usb chip( idVendor = 0x0a5c, idProduct = 0x200a). It advertises SCO
mtu=16, sco packets = 0.
I tryed to use it with SCO, no luck.(I wasn't surprised by that, given
sco packets = 0) Then i looked at hci usb driver and found it was in the
blacklist, with HCI_BROKEN_ISOC.
I then removed it from this list, forced SCO mtu to 48 and packets
number to 8 by hacking hci_event.c... and guess what, it works !!
So my question is: shouldn't this product marked as HCI_WRONG_SCO_MTU
mtu instead of HCI_BROKEN_ISOC?
Cheers,
Fabien

is it enough to change HCI_BROKEN_ISOC into HCI_WRONG_SCO_MTU to make
this work. If yes, then I am happy to submit a patch.
