Hello,
Trying to use OsmoTRX (osmo-trx-usrp1) with USRP1 SDR,
this is great news, thanks for looking into this. I don't think anyone in Osmocom has been using a USRP1 for quite some time, so your mileage may vary.
It would be great to iron out the problems you experience and ensure continued support of this old SRD platform.

This is probably the key here. The firmware file for the USRP1 device was not found. You could strace osmo-trx-usrp1 to see where it expects that file, and then try to put it in the right location.
It seems that our libusrp.git doesn't include that file, thought.
UHD ships the file at /usr/share/uhd/images/usrp1_fw.ihx, but I'm not sure if it's compatible with old libusrp.
I think the firmware used to be built together with libusrp, but I don't recall the details.. It's been so many years back.

I've now been working on a series of patches to ensure we build + package the std.ihx firmware file as part of libusrp.
See the 'laforge/firmware' branch of libusrp.git. I've also pushed the patches to gerrit for review.
NOTE: I've not tested any of this with a USRP1 yet.
