Support for Nuand BladeRF A4

Hi there,

I purchased a BladeRF 2.0 xA4 direct from Nuand a few years ago and recently I cannot seem to get it to work on Windows or Linux. The firmware is all up to date, and I’ve sought help from Nuand but with no success. We troubleshot for about 5 days and I’m still unable to use any SDR software. It’s out of warranty so I can’t send it back.

Windows recognises the device but in the device manager log it gives me a “Device not started (WinUSB)” error with additional info relating to either oem6.inf, oem11.inf or oem15.inf.

The error information is:

Device USB\VID_2CF0&PID_5250\34168397a28441549dfb7f775baf48cc had a problem starting.
Driver Name: oem15.inf
Class Guid: {88bae032-5a81-49f0-bc3d-a4ff138216d6}
Service: WinUSB
Lower Filters:
Upper Filters:
Problem: 0xA
Problem Status: 0xC000000E

Under Linux, PyBombs is fully installed and the device is recognised under “lsusb” as Bus 008 Device 002: ID 2cf0:5250.

When I run GQRX, CubicSDR or SDRSharp, none recognise the device and I can’t use it.

Hoping someone has come across this before?
