Dear Gy-Chou,

we run a PerkinElmer VoX since quite some time in the ALMF at EMBL Heidelberg. As far as I know we don´t have the problem you are describing. I would recommend to install the newest Volocity release first and if this doesn´t help check if there are any other problems on the PC. 
Maybe it already helps to plug the prosync into another USB port ?

Did you install any other software/drivers on this machine, which are not related to Volocity !? We usually don´t install any other software on microscope PCs and rather analyze data on separate workstations.

If all the above don´t solve your problem I would call the service, we have good experience with the service and it might still be under warrantee (I guess you are using a PC bought from PerkinElmer !)?

Hope this helps,

best regards,

Stefan
