* util-linux/lsusb.c: print manufacturer/product strings if availablePeter Korsgaard2023-12-131-1/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Just listing the vendor/product IDs is not always very helpful, so add logic to print the manufacturer and product strings similar to the "big" usbutils versions. Not all devices provide sensible strings though. The usbutils version works around this by falling back to looking up the vendor/product IDs in the hwdb and using those strings instead, which is not an option here - Instead simply trim() the strings for readability. lsusb | sort Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 002: ID 0bda:5539 Realtek Semiconductor Corp.

Example of parameter get use: $ hwclock -g 2 The RTC parameter 0x2 is set to 0x2. $ hwclock --param-get bsm The RTC parameter 0x2 is set to 0x2. Example of parameter set use: $ hwclock -p 2=1 The RTC parameter 0x2 will be set to 0x1. $ hwclock -p bsm=2 The RTC parameter 0x2 will be set to 0x2. function old new delta hwclock_main 298 576 +278 .rodata 105231 105400 +169 packed_usage 34541 34576 +35 static.hwclock_longopts 60 84 +24 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 4/0 up/down: 506/0) Total: 506 bytes Signed-off-by: Andrej Picej <andrej.picej@norik.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
