So there were no help from new kernel in Hardy. I found a suitable fix for this: In vanilla kernel source changing instance in file drivers/bluetooth/hci_usb.c does the trick.
Under comment
/* RTX Telecom based adapters with buggy SCO support */
A new line is added:
{ USB_DEVICE(0x0e5e, 0x6622), .driver_info = HCI_BROKEN_ISOC },
I hope this helps.
