[Bluez-users] 3 or more BT dongles over 1 USB-2.0 4-port HUB

[Bluez-users] 3 or more BT dongles over 1 USB-2.0 4-port HUB

[Petr Palacký]

Hi all,

i have problem with three (and more) USB BT dongles (all are the same, 
CSR-based) and 4-port USB-2.0 HUB.

When i attach one USB dongle alone, everything is good (hci0 is up and 
running). When i attach the second dongle (after the first), still is 
everything OK (hci0 and hci1 are up and running).
But when i attach third (or fourth) dongle, this does not work.

I tried attaching all dongles differently but every time the third (or fourth) 
dongle is not OK and dmesg says:
#dmesg
hci_usb_intr_rx_submit: hci2 intr rx submit failed urb cd55b674 err -28

If i have attached all four dongles only the first two are OK, if i manualy 
change its state to "DOWN" and next two to "UP", now i have also hci2 and 
hci3 working (but never all three or more along).

If i have state for the first two dongles "UP" and trying setting up next two 
dongles "UP" also, then i get message:
# hciconfig hci2 up
"Can't init device hci2: Input/output error (5)"

I also tried another USB-2.0 HUB, but everything is the same - nothing 
happens.

When i attach two dongles and second USB HUB (with one or more dongle 
attached) into first USB HUB, everything is OK. Now i have all three or four 
dongles working, but this isn't good solution.

If i attach two dongles, one printer and one mouse into this (or my second) 
USB HUB, evereything is good and all devices are working, so these HUBs are 
good.

I tried this procedure on four different computers (3x PC, 1x Laptop - all 
with linux-2.6.x with distros Gentoo, SUSE and Debian), but still nothing 
happens.

Please, is there any way how to run more than two USB BT dongles attached to 
one 4-port USB-2.0 HUB?

Thank for any idea

try loading the hci_usb driver with the isoc=0 option. This maybe helps,
but it can also be a general problem with your USB root hub. In that
case you have to check with the USB guys, because this is not Bluetooth
specific.

Marcel

Hi Marcel,

thank you for your tip.

I tried loading hci_usb with option isoc=3D0, but still nothing happens.
I don't think if this is question for USB Guys, because other devices eg.
printer, mouse, keyboard, flash-disk etc. works fine and all together
attached into one USB HUB.
I think this is problem with any component from bluez stack...

Petr

Could it be a power problem? maybe your USB port can't supply enough
power to all the devices.

Re: [Bluez-users] 3 or more BT dongles over 1 USB-2.0 4-port HUB

[petr]

Hi Jamie,

my USB HUB is with and can also operate without power supply.
Today i tried these HUB and dongles on the ARM board with Debian Linux and
kernel 2.4 and here can i set "UP" only one dongle (with or without extra
power supply).
This looks as hci_usb doesn't like USB 2.0 standards...

Re: [Bluez-users] 3 or more BT dongles over 1 USB-2.0 4-port HUB

[SZABO Tamas]

hi Petr,

I was realising the same problem but in case of USB-Serial
converter. The solution for me was to remove ehci-hcd and
using the full speed uhci-hcd driver only. I think the lower
12MB/s speed  can not be a problem for BT.

Good luck!

PS: Sorry, I don't now how to reply on the sourceforge page,
it is readonly although I logged in. So this may start a new
thread.
