[bitbake-devel] [PATCH 2/6] ui/crumbs/hig.py: fix run time error

[Kang Kai]

Commit 094742bed2fc01d55f572da946fcfa7a48521401 re-implement the
function popen_read(). If there is no USB device, it crashes with
"ExecutionError: Execution of 'ls /dev/disk/by-id/usb*' failed with exit
code 2:"

Replace popen_read() way with glob module to get the USB devices.
