Description

openbh 5.0.011 (2022-03-08) looks for /usr/bin/bcm3148 (trailing space) instead of /usr/bin/bcm3148

Steps to reproduce

1. Install OpenBh 5.0, specifically 2022-03-08) on a Vu+ Duo 4K SE BT equipped with one DVB-C tuner card and one DVB-T2 tuner card. Since I have no plans to use the hardware's Bluetooh functionality, I picked openbh-5.0.011.release-vuduo4kse-1205265b_usb.zip without worrying whether I need bt in the image name or not.
2. Attempt to Service scan the DVB-C tuner (currently there is no antenna connected to the DVB-T2 tuner)

Actual result

E2 shows the following error pop up

Cable scan executable utility not found '/usr/bin/bcm3148 '!

Expected result

E2 calls the scan binary without a trailing space

Additional info

Workaround

Primitively worked around by copying /usr/bin/bcm3148 to one with a trailing space (/usr/bin/bcm3148)

root@vuduo4kse:~# cp /usr/bin/bcm3148 /usr/bin/bcm3148\ 
root@vuduo4kse:~# ls -l /usr/bin/bcm3148*
-rwxr-xr-x    1 root     root         12426 Feb 13 22:40 /usr/bin/bcm3148
-rwxr-xr-x    1 root     root         12426 Mar 13 17:29 /usr/bin/bcm3148 
root@vuduo4kse:~# 

After doing that, I can trigger a Service scan just fine in E2.
