Bug ID: 289242
Summary: usbconfig needs to be run as su // or does not return
error (libusb20)
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: usb
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
When usbconfig is run as user it gives a generic warning:
% usbconfig
No device match or lack of permissions.
% echo $?
0
There are multiple problems with that:
(a) apparently a user cannot dump the list of devices like one can for pciconf
-l
(b) usbconfig (if lacking permissions) returns 0 (no error) so other scripts
cannot easily detect this; flush_command() is void; parsing the output line for
this specific message helps but is broken by desin
(c) I cannot see an easy way to detect if it is a permission problem (rather
than no matches) to do an early exit.
Solving (a) would solve some of the problem (at least for listing; the use case
I am currently after) but not the general problem as a user might still not be
allowed to do:
% usbconfig -d 0.2 reset
No device match or lack of permissions.
% echo $?
0
So having a way to say: no such device vs. permission denied + non-zero exit
code in either case would still be better.
