[linux-dvb] Bug: Usage counter of module dvb_usb_dtt200u (Device: WideView WT-220U PenType Receiver)

[Matthias Schwarzott]

Hi There!

I have these days a dvb-t stick of a friend to test it with Linux and vdr.
Now the first bug I discovered (using v4l-dvb-hg).

Operations:

Loading dvb-usb-dtt200u (Usage Count: 0)
Plugging the device in (usage Count: 0)
Unplugging it (Usage Count: 4294967294)
Plugging it in (Usage Count: 4294967294)
Second time unplugging (Usage Count: 4294967292)

Observation: Plugging it in does not change usage counter.
Unplugging decrements it by two.


Part of dmesg:
DVB: registering new adapter (WideView WT-220U PenType Receiver 
(Typhoon/Freecom)).
DVB: registering frontend 2 (WideView USB DVB-T)...
input: IR-receiver inside an USB DVB receiver as /class/input/input6
dvb-usb: schedule remote query interval to 300 msecs.
dvb-usb: WideView WT-220U PenType Receiver (Typhoon/Freecom) successfully 
initialized and connected.
dvb-usb: recv bulk message failed: -110
usb 5-6: USB disconnect, address 6
dvb-usb: WideView WT-220U PenType Receiver (Typhoon/Freecom) successfully 
deinitialized and disconnected.
dvb-usb: WideView WT-220U PenType Receiver (Typhoon/Freecom) successfully 
deinitialized and disconnected.



Notice the one line for connect and the two for disconnect.

More bugs will follow ;)
