Using the latest USB Redirector for Linux - 3.6, have a server and client "seemingly" configured yet not working.

Installer ran with absolutely no issues, the software 'appears' to work (as in the client connects to the server and reports the device as 'connected'), USB device shows up on client-system via lsusb, etc.. ** ... However, keyboard is unresponsive as if not connected to the client system.


Server System: Xubuntu 16.04 on Raspberry PI-2B, kernel -- 4.4.47-v7+ armv7l
Client System: Xubuntu 16.04 on PC, kernel -- 4.4.14-040414-generic x86_64

On Client:
lsusb
Bus 003 Device 002: ID 04d9:a0cd Holtek Semiconductor, Inc.

usbclnt -l
USB CLIENT OPERATION SUCCESSFUL
...
`- 3: USB Keyboard Composite USB Device
Vid: 04d9 Pid: a0cd Port: 1-1.5
Mode: auto-connect Status: connected

I've tried on kernel 4.9.8 (which the installer runs on without issue -- both on the RPI and on the client-system). I've additionally tried a USB Flash Drive, yet this doesn't seem to be working just like the keyboard.
=> Device shows up in lsusb, reports 'connected'. Drive is not mountable and fails / hangs at here.

-It may additionally be worth mentioning that the Xubuntu PI image is via Ubuntu PI Flavor Maker. [ https://ubuntu-pi-flavour-maker.org/download/ ]
-Keyboard in question is an Eagletec ET-KG010.

EDIT: Network between devices is just wired-LAN. (nothing special)
Plugged another device in for testing.
Bus 003 Device 003: ID 046d:c51b Logitech, Inc. V220 Cordless Optical Mouse for Notebooks

--This one is interesting. Mouse buttons don't work, moving the mouse causes the mouse cursor on the client to rear to the right (yet no other direction). Something is being received at least.

More testing:
Removed USB Controller from client, so that USB devices are only connected via USB Redirector.

Eg, all devices as follows on system startup:

lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 04d9:a0cd Holtek Semiconductor, Inc.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
-Sadly no change.

-Disabled UFW for the sake of it, despite having 32032/tcp open.

^ Any suggestions where to start on troubleshooting?
Thanks!

Update:
*** Further narrowed this down, yet still no solution found ***
--Whatever the problem is appears to be the "client" and not the server. (Windows client on another machine works just-fine)
--VirtualHere, has the same issue from Linux => Linux, and also works on the Linux => Windows usage. (doesn't just effect USB Redirector)
--It does not appear to be the hardware of the client system, as I just converted that machine to a VM ran through VirtualBox. (same issue)

Absolutely: Here's a dmesg dump from VMWare running the image. (same result as when I ran it from VirtualBox with USB disabled)


--Will do a full wipe of the physical-machine and a clean install of 16.04 over the course of today to try to get to the bottom of this. I'm sure your software should work smoothly considering some of the others are not as well. Something is definitely funky with this install, although sadly nothing stands out to me so far.

The only that's seemed to work so far per that install is the fairly outdated USB/IP. (other than the integrated USB of course)

Update:

While I still don't know what happened on that last install of Xubuntu, whatever it may be we now know that something was broken packages wise.

-First did a fresh install of Linux, installed nothing other than USB Redirector. (USB Redirector immediately worked)



Moving back over to the broken installation:
Did an apt-get --get-selections on the broken client image, wrote a bash-script to loop over every package, and then basically called "apt-get --force-yes install --reinstall $PACKAGE -y" for everything on the system.
^ That did the trick, so some package wasn't installed properly or was corrupt in some way.


Oddly enough had no errors during the first time around, so I guess I'll take a look at the hardware of that machine (test the memory, etc)... Anyway, we can consider this a fluke / SOLVED now, doesn't look like redirector was at fault in any way.

Yeah, that sounds odd. It could be a problem in udev rules which control driver loading, configuration files, or some of the kernel modules that did not work properly. Re-install has probably reset them to defaults.

Anyway, we are glad that the problem is resolved! Thanks for update!
