I have the following bluez modules loaded: - hci_usb 8088 1 bluez 32356 1 [hci_usb] hciconfig hci0 down No interrupts from the bluetooth device. hciconfig hci0 up About 100 interrupts per second from the bluetooth device. hciconfig hci0 down No more interrupts from the bluetooth device. There is no actual data coming from the bluetooth device, as I can check with hcidump. We get a few lines of output at the transition from up to down and down to up, but nothing in between. Is this activity normal? Does is happen with the PC card or PCI card usb adapters ? It seems to me that these interrupts should not be there.
Do you have SCO support compiled it ? Also USB is a pulled bus. ie HC pulls device. When we bring device up we submit URB read requests. I believe those can trigger interrupts even if there are no actual transfers.
