is the connection time limited ?

Submitted by avillegas on #1

Hi,
I'm trying the trial version of Virtualhere server on a Raspberry Pi 3+.
The USB device connected to the Raspberry is an ECG recording hardware from NORAV Medical which acquires and streams USB data continuously.
I'm able to see the USB device from the client (a laptop running Windows 7), connect to it and record data on the laptop just like the USB device is directly connected to the laptop. Easy to install both server and client sides, amazing job from you.

After about 1 hour of using it, the software for ECG acquisition seems to lose connection with the virtual USB device and then stop working.
So, I was wondering if the trial version of the server has limitations when accessing isochronous USB devices for a long time.
Is it possible to keep the connection alive and transferring data without interruptions nor data corruption for 3 or 4 hours continuously?

Thanks

VirtualHere is rock solid for transferring data, are you connected over wifi? Perhaps thats dropping momentarily.

(Also i would recommend using win10 as win7 wont be supported soon, by me or Microsoft)

Thanks Michael for your reply
Yes, I'm using WiFi. I also think the WiFi may be dropping and causing the problem.
Any recommendation about how to check that? Perhaps some log on the Raspberry I could check?

In the client when it drops, right click USB Hubs->System messages and it will say the reason there
