Hello,
I got an acer dongle (BT-510) containing a zeevo bluetooth chip.
This zeevo-dongle obviously works not so well with bluez as it keeps
crashing with segfault.
The system I use should be well-configured, as everything works fine
with csr-based devices (acer BU2 dongle).
So, is the zeevo-chip not supported, can it be fixed anyway?
Thanks,
Maximilian Michel

this is correct. No ISOC endpoints, no SCO transfer, no voice.

OK, compiling with latest patch with quirk helped, can use the dongle now.
But I think, I can never user voice with this dongle as it would need
sco support?
Thanks,

and this is what I mean. They don't read the H:2 spec. and push out an
invalid product, because at least it must have this entry:
I: If#= 1 Alt= 0 #EPs= 2 Cls=e0(unk. ) Sub=01 Prot=01 Driver=hci_usb
E: Ad=03(O) Atr=01(Isoc) MxPS= 0 Ivl=1ms
E: Ad=83(I) Atr=01(Isoc) MxPS= 0 Ivl=1ms
You can use one of my patches with this changelog entry
- Quirk for devices with no ISOC endpoints
or you disable SCO support for the hci_usb driver at compile time.

Marcel

if I remember correctly, the Zeevo chip is one of these buggy Bluetooth
devices which have no SCO endpoints. Please send us the output of
/proc/bus/usb/devices and try one of my latest -mh patches or the latest
2.4.22-pre.
Regards
Marcel
