Mike,
In my previous text I was simply trying to describe two problems
that I observed
with the latest driver snapshot that I could find on your web site. The
snapshot dated 31st October 2009.
The two problems I see are:
1. The HVR-1900 device attributes does not have the 16K firmware bit
set. Although the HVR-1950 does.
2. The test add the end of the firmware upload prevents a 16K upload
from succeeding.
Sorry if my description was not very clear.
Is there a later snapshot of the driver than the one I referred to above?

The driver has already been updated (and since the HVR-1950 has BOTH
16KB and 8KB firmware floating around the actual fix is slightly more
complex than simply checking for 16KB in place of 8KB).
However there is a lag before the in-kernel version is going to pick up
the changes. In the mean time you can grab the latest standalone driver
which includes the needed changes. See here:

The documentation is also already updated to describe this situation.

Hi Mike,
Firstly, thanks for all the effort in maintaining drivers for the pvrusb2.
I recently acquired an HVR-1900 and now have it working with both Ubuntu
9.04 and Slackware64 13.0, except for the IR Blaster. Using the extract script
from the 20091031 snapshot I was able to extract the required firmware, but
had a couple of problems in using the latest FX2 firmware.
The firmware for the HVR-1900 (From 1.2a driver CD) is now 16k in size. To use
this required two changes to the driver source.
1. The addition of the 16k flag for the HVR-1900 in pvrusb2-devattr.c.
*** 393,398 ****
--- 393,399 ----
.flag_has_analogtuner = !0,
.flag_has_composite = !0,
.flag_has_svideo = !0,
+ .flag_fx2_16kb = !0,
.signal_routing_scheme = PVR2_ROUTING_SCHEME_HAUPPAUGE,
.digital_control_scheme = PVR2_DIGITAL_SCHEME_HAUPPAUGE,
.led_scheme = PVR2_LED_SCHEME_HAUPPAUGE,
2. The firmware uploader pvr2_upload_firmware1 in pvrusb2-hdw.c checks is
hardcoded to check for an 8192 byte upload, causing a 16k upload to fail. I
changed this to use the actual size of firmware expected.
*** 1890,1897 ****
trace_firmware("Upload done (%d bytes sent)",ret);
! /* We should have written 8192 bytes */
! if (ret == 8192) {
hdw->fw1_state = FW1_STATE_RELOAD;
return 0;
}
--- 1890,1897 ----
trace_firmware("Upload done (%d bytes sent)",ret);
! /* We should have written fwsize bytes */
! if (ret == fwsize) {
hdw->fw1_state = FW1_STATE_RELOAD;
return 0;
}
Keep up the good work
Gary
