[Bluez-users] ARM-linux and multiple USB dongles

Hello all,
 
I'm facing this problem on ARM-linux (2.4.26) and 2 USB dongles on a
TS-7200 SBC by technologic systems.
 
When I plug the 1st dongle, it is correctly initialized and it works
okay.
When I plug the 2nd one, it is regognized but I can't get it working:
hciconfig hc1 up returns timeout(110).
 
If I unplug hci0 (the first dongle) then hci1 starts working.
 
I have been trying this with different dongles & different chipsets but
I still get the same results.
On the development machine (i86 with same Kernel version) everything
works ok.
 
At the beginning I thought this might be some problem with USB support
on the board. But I have been able to operate up to 7 simultaneous USB
devices on the board (not bluetooth) and they work ok.
 
Are there any known issues about multiple devices and ARM? 
 
Thanks in advance,
Francesco

no, they are working perfectly. Why don't you try to use a recent 2.6
kernel on your system. Sticking to 2.4 is not a good idea at all.
