ElbopeepI am an Arca Noae reseller, and I have a few computers available for sale. This is one of them. I thought I'd report on the behavior of the ArcaOS 5.0.5 installation and USB 3.0. My computer web pages can also be used as a guide to install ArcaOS yourself.
http://www.blondeguy.com/computer/elbopeep.htmlManufacturer: Lenovo
Model: Thinkpad X250
CPU: Intel Core i5-5300U (2.30 GHz)
Screen: 12.5 inch Color LCD, 1366 x 768 pixels
USB 3.0 controllers: 1
USB 2.0 controllers: 1
Arca Noae USB driver stack 12.06 is installed. With the USB 3.0 Enabled setting in BIOS on Auto, mouse and keyboard sometimes work, even with KVM. Support for Mass Storage similarly sometimes is working. With USB 3.0 disabled in BIOS, USB 2.0 support is working with Mass Storage. Mouse, keyboard and KVM work sometimes.
Normal operation of the laptop does not require USB. The built-in mouse and keyboard are not USB.
This is a small laptop. There is no support for the built-in WiFi. I use a travel router connected to the Ethernet port. To me, the travel router has more and better capability than XWLAN. The router uses GL.inet software controlled by a web interface that runs just fine in Firefox.
