Problems with Wacom STU-500 signature tablet

Hi
We have the tablet, mentioned in topic subject. And we are working via RDP, so the device itself is connected to the local machine, and the client software is installed on the remote computer.
When the signature is being taken, it seems that some "points" are lost, so that when I look on the tablet screen - the signature is smooth and natural, but in the "result window" it's very angular, like zigzag.

Wacom support says, that if the data is 100% tranferred, it should not bee the issue for the tablet driver to display it correctly, even if there is slight delay in delivery.

We are testing your software for 3 or 4 days, trying to achieve decent quality on the tablet screen, but unsuccessfully, so i think i need help or advice. Versions: UoN - 4.7.4, USB Monitor - 2.7

I'm analizing USB monitor data, and as i can see, not all the data matches correctly, some "events" have pair, some events don't. They have different order, on the "source" side we have IN,IN,OUT,OUT ... on the "destination" side - IN,OUT,IN,OUT. On the "source" side Hdr.Length is 0x48, on the "destination" it's 0x80, and othre differences.

Is it possible that UoN loses some data? or maybe there are some tunings, that i can try to adjust? Or maybe there are some known issues. We tried on 3 different computers, the result is the same.

Greetings,

Thank you very much for provided information. We are aware of this issue and already working on its solution.

Please specify one detail. You mentioned you work via RDP. I need to know do you need to use the device in zero session on the computer where USB over Network(client) is installed?

Thanks.

Hi

About zero session - no, we don't need it at the moment. We have a group of terminal servers and a bunch of users, working on them. One of the users is going to use the tablet to receive signatures, and this user will not work in a zero session, it'll be average session as every other user is using.

If you are aware of this issue, can I ask when do you plan to fix it?
It's important for me to know because if update will soon be released, then it'll be reasonable for me to wait some time. And if the date is undetermined yet, I'll probably rewrite my software part to client-server architecture
Thanks

"USB over Network" v. 5.0 will be ready in 2-3 weeks and "USB for Remote Desktop" v5.0 should be ready within 2 months. I hope this term is not a problem for you.
