[pvrusb2] WinTV-HVR-1950 can't load firmware in Ubuntu 10.04

[Jeff Caldwell]

I have a WinTV-HVR-1950 that was working perfectly in an Ubuntu
version maybe 3 OS upgrades ago. I quit using the 1950, with MythTV,
for awhile so I'm not sure when it quit working. I just upgraded to OS
10.04 and am trying to get the 1950 working again. I looked through
maybe 25 pages of the mail list search and didn't see what I need,
sorry if my glazed-over eyes missed it.

I found a link somewhere to what was referred to as a new FX2 firmware
file. I diff'd mine against it and they were the same.

I made a single-channel scan file for me-tv and it got a signal lock
on a 581 MHz station that I can watch with my digital antenna plugged
directly into the TV. That left me-tv in a configured state for that
channel and device. Every once in awhile I can get me-tv to start, use
that channel, get a signal lock, and show a single, frozen, scrambled
video frame. That seems to have fallen by the wayside, though, and now
all I get is the following:

When I run me-tv I get many instances of the following in
/var/log/messages (many as in "/var/log/messages is 1.7Gb full of the
following message):

 pvrusb2: Attempted to execute control transfer when device not ok

I unplug the USB cable and get:

 usb 1-6: USB disconnect, address 20
 pvrusb2: Device being rendered inoperable

Power down the 1950 and power it back up, plug in the USB cable and get:

usb 1-5: new high speed USB device using ehci_hcd and address 21
usb 1-5: configuration #1 chosen from 1 choice

It just sits there. I run me-tv and it immediately goes back into the
Attempted to execute control transfer message loop. Previously I would
get in /var/log/messages, after replugging the USB cable:

Thanks for the driver and thanks for any suggestions.
