View all threadsB205 mini-i isn't found by uhd_find_devices
Hi everyone, I'm just starting out with the USRP B205 mini-i, and I'm having some issues.
I'm running Ubuntu 20.04 LTS, I've also installed the UHD toolchain using the instructions on the Ettus website (Building and Installing the USRP Open-Source toolchain (UHD and GNURadio) on Linux. The UHD version is v4.0.0.0.
So, after installing UHD and running the 'make test' diagnostic, everything passes 100%, so it seems like everything is working correctly. I've also made sure that the 'uhd-usrp.rules' file has been copied to the /etc/udev/rules.d directory.
When I plug in the B205 mini and do a 'lsusb', it finds a device with the VID/PID of 2500:0022 called "Cypress WestBridge". This is the B205 because when I unplug and run 'lsusb' it disappears, then if I plug it back in it reappears. Great!
So next I try 'uhd_find_devices' and it finds nothing. It returns with:
[INFO] [UHD] linux; GNU C++ version 9.3.0; Boost_107100; UHD_4.0.0.HEAD-0-g90ce6062
No UHD Devices Found
Questions:
-
Should the uhd-usrp.rules have a specific entry for the B205?
-
Is is correct that the B205 comes up as a "Cypress WestBridge"? I know it's the B205 because when I unplug it, it disappears, and when I plug it back in, it reappears.
-
uhd_find_devices does not throw any errors, it just doesn't find the device, could there be a hardware problem?
Any help is appreciated, thanks!

My "rules" file has the following for B2xx devices:
#B200
SUBSYSTEMS=="usb", ATTRS{idVendor}=="2500", ATTRS{idProduct}=="0020",
MODE:="0666"
SUBSYSTEMS=="usb", ATTRS{idVendor}=="2500", ATTRS{idProduct}=="0021",
MODE:="0666"
SUBSYSTEMS=="usb", ATTRS{idVendor}=="2500", ATTRS{idProduct}=="0022",
MODE:="0666"
SUBSYSTEMS=="usb", ATTRS{idVendor}=="3923", ATTRS{idProduct}=="7813",
MODE:="0666"
SUBSYSTEMS=="usb", ATTRS{idVendor}=="3923", ATTRS{idProduct}=="7814",
MODE:="0666"
You could try:
uhd_usrp_probe --args type=b200
If that fails, try again as root.
If it works as root, then you have a rules issue.
Thanks for the response,
My rules file is the same as yours.
I tried what you suggested as both user and root and the response for both was:
Error: LookupError: KeyError: No devices found for ——->
Device Address:
type: B200
It’s very frustrating because ‘lsusb’ sees the device, so I don’t know what else the problem might be.
I've had this issue before too. It is worth noting that you can reset the
USB interface programmatically.
See https://askubuntu.com/a/661 for an example.

Thanks Dustin,
Did resetting the USB fix your problem?
I don’t think I’m having any USB issues per say, I can plug the B205 in and after doing an ‘lsusb’ I can see the device on the bus. The problem I’m having is that when I do a ‘uhd_find_devices’ it doesn’t find anything. My gut feeling is telling me that there’s an issue with the hardware, but I’d like to exhaust any other possibilities before trying to debug the actual B205 itself.
Oh, it seems I may have misread your email, particularly the bit about it
"reappearing" after unplugging/replugging it (resetting the interface
programmatically had the same effect). The issue I had is that
uhd_find_devices would work again after doing that ... Sorry for the
distraction.

I’ve been poking around trying to find out any more information on my issue and I noticed this after running the ‘usb-devices’ command:
T: Bus=01 Lev=01 Prnt=01 Port=01 Cnt=02 Dev#= 10 Spd=480 MxCh= 0
D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
P: Vendor=2500 ProdID=0022 Rev=01.00
S: Manufacturer=Cypress
S: Product=WestBridge
S: SerialNumber=0000000004BE
C: #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=200mA
I: If#=0x0 Alt= 0 #EPs= 0 Cls=ff(vend.) Sub=00 Prot=00 Driver=(none)
The VID/PID are 2500:0022 so this is the B205 I have plugged in, but on the very last line it says “Driver=(none).
Could there be something wrong with the UHD installation? Should I try a different version than v4.0.0.0?
What does dmesg report when you plug the device in?

This is the output of ‘dmesg -wH’ after plugging in the B205.
