After a few try and fails to build heavy-duty turntable for scanning a whole person I came to an idea to use something that was designed to withstand the weight of an adult person.
Ubuntu 15.10 contains usbip package too old to work with usbip v2.0 server (e.g. latest raspbian on RasPI) so you need to compile usbip tool from kernel sources.
You don’t need to go through compiling from source. You may just install package linux-tools-generic:
$ apt-get install linux-tools-generic
This will install precompiled usbip tools into /usr/lib/linux-tools/`uname -r`/:
$ /usr/lib/linux-tools/4.2.0-35-generic/usbip version usbip (usbip-utils 2.0)
$ sudo usbip -l 192.168.1.83 - 192.168.1.83 usbip err: usbip_network.c: 119 (usbip_recv_op_common) recv op_common, -1 usbip err: vhci_attach.c: 202 (query_exported_devices) recv op_common usbip err: vhci_attach.c: 417 (show_exported_devices) query $ usbip -v ** (process:30826): WARNING **: running non-root? usbip 0.1.7 ($Id: vhci_attach.c 42 2007-09-07 12:07:51Z hirofuchi $)

Thanks to a tip of my reader, I found a relatively cheap (69Eur) Android box with HDMI input and record ability. I thought that it should be possible not only to record the HDMI input but also to stream it in realtime so I ordered one for experimenting.

I needed to backup original firmware of my favorite Chinese wireless router but I didn’t want to spend much time with hacking the embedded Linux. So I have ordered this cheap USB serial EEPROM programmer on ebay. You can easily find the original utility & driver for Windows on the Internet but the chip manufacturer doesn’t provide software for Linux.
