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?
