Hello fellows,
I have an HPLP2475w screen who can act as an external Usb hub when I link it with a dedicated Usb cable to one Usb connector of the computer. The screen have 6 Usb connectors. I have a Logitech Usb receiver, a Sony Usb stick and an Alcor Usb webcam plugged to three Usb connectors.
When I boot the Efi/Bios see my Logitech Usb receiver and my Sony Usb stick connected to the screen, I can enter in the Bios and nagivate with my keyboard even boot from the Sony stick. Everything is good. When I boot on Linux he see the devices connected to the screen and give me access to my keyboard and mouse only. He see the Sony stick and the Alcor webcam but give me this messages
Linux list all connected devices to the screen but to access to the Sony and Alcor ones I have to pass those two command in the Sysfs
Than I can use all three devices connected to the screen. I have no problem with any of them.
Here I come. When I boot to FreeBSD he do the same basically then Linux. He give me access to my keyboard and mouse but not to my Sony and Alcor devices. All the Usb devices are correctly listed when I execute the usbconfig command including the ones on the screen. I have try some commands using usbconfig but none of them give me access to my Sony and Alcor devices. Is someone can tell me if I can use more then one device from this external Usb hub and if yes how please. My search on Internet have give me no successful results.
