Hi all,
I am recently playing with software
defined radio (SDR) hardwares (USRP, bladeRF, etc.),
and come across the plugdev group issue. It seems the best way is to
write a local rule
saying something like: [1]
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", \
ATTRS{idVendor}=="xxxx", ATTRS{idProduct}=="yyyy" \
ENV{ID_<some_name>}="zzzz"
and to rely 70-uaccess.rules [2] to grant the permission.
However, it seems there is no proper ID for SDR hardware for the
moment, so I have to
write TAG+="uaccess" directly in local rule file. AFAIK it is not recommended.
So is it possible to add ID_SDR_HW in the 70-uaccess.rules file?
You may suggest a better name of course.
Besides, I see there are inconsistency of ENV{ID_<some_name>} in [2]
("*?" vs "?*").
Do they match different things? Hope you can clarify.
