We have started receiving shipments of HP 6540b ProBook laptops. EEPC v5.1.8 installs ok but when connected to a docking station with a USB keyboard & mouse the usb devices are not working at the PBA login screen. We have to open the laptop cover and use the built in keyboard and touchpad in the PBA. The O/S is Win XP Sp3, everything works ok once logged into Windows. Any ideas or config we're missing?
USB mouse not working is a known issue for 5.x systems, use keyboard instead.
But external USB keyboard should work. Check BIOS and machine object property settings.
As I recall there was enhancement for USB pre-boot control and hand-over to OS in EEPC 5.2.3. Now we have 5.2.4 with 5.2.5 coming.
I would suggest to get 5.2.4 and test it with your hardware.
