Support

Hey there,

is there a limitation for the maximum number of devices connected to one client at the same time?

I have a virtualhere server running on a raspberry pi b+. On each USB port of the pi there is a 4-port usb hub. One each port of this hub there is another 4-port usb hub. On this four hubs there are 15 usb to serial converters connected. All together ther are 60 usb to serial converters connected to the raspberry pi and 20 usb hubs.

Good morning all,

Firstly I wish to say this software is a brilliant solution for sharing my USB software security dongles over my LAN - love it :)

Hi,
I got this error message when I try to connect to the following the following device I get this error message from the server side

Hi - is there a user guide?

I've read various sticky topics, and searched, but in particular I'd expect something written about theory of operation (e.g. how it modifies and interacts with standard USB configuration), limitations (do hubs make a difference), troubleshooting procedures (at the client and server end, e.g. increasing logging) and what the error messages mean.

Thanks, Martin

I have a sketch (I'll paste below) that I install on an ArduinoUno that simply reads 8 bytes over the serial connection, and then echos them back. I communicate to the Arduino via PuTTY. This works fine with a direct connection, but when connected over VirtualHere, I end up losing the first few bytes on the reply. It's not consistently the same number of bytes lost, but it's usually 1-4. After that, communication seems to work OK.

I just noticed the existence of virtualhere and installed the trial version on my QNAP server.
While looking through the forum I also noticed that El Capitan is not supportet - just wanted
to know whether this is still the case?

Thanks for you insight,

Tom

VirtualHere USB Server: 3.6.6 (Windows 64-bit)
VirtualHere Client: macOS

I am trying to access a VISA device (specifically, a B&K 9201 power supply) using VirtualHere. The device is physically connected to a Windows computer, and I am trying to access it from my MBP. The client on macOS pops up an error window "There was a error using this device." The server on Windows shows the following in the server log:

I've been testing out some high bandwidth USB boards with USB 3.0 support on a 4.9.0 kernel Linux x64 server and a Windows 10 client. I gave them a wired 1 GigE connection directly between them. The speeds were way better than the tests I ran over USB 2.0 but still slower than a direct connection. My question is:

Assuming these are the speeds in an ideal world, is my 1 GigE network a bottleneck?
USB 2.0: 480 Mbit/s
USB 3.0: 5 Gbit/s

I can't use VirtualHere with a Mayflash Gamecube adapter without it having sever lag spiking.

Hello,

I have 3 machines with Windows 10, that was using VirtualHere Client, and notice that after Windows update has been made in 2 machines, that no longer connect to usb server.

I have update to VirtualHere Client 4.5.2, on those 2 machines after notice this issue.

Do you know a way to solve this?
