Understanding the Customer Module is best done through the context of a support session:
Even with stable software, network variables cause friction. Here is how to fix them.
| Symptom | Likely Cause | Solution in v1.9.7 |
| :--- | :--- | :--- |
| "Unable to connect to server" | Firewall or port forwarding missing | Ensure TCP port 32032 is open outbound on customer network. Test via telnet tech-server-ip 32032. |
| Device connects but disappears after 30 seconds | USB isochronous timeout | In Client settings, increase "Keep-alive interval" to 5000ms. |
| "Driver error - Device cannot start (Code 10)" | Virtual USB driver conflict | Uninstall old USB Redirector versions via Device Manager → View hidden devices → Remove ghosts, then reinstall v1.9.7. |
| High latency (mouse/keyboard lag) | Network RTT > 100ms | Enable "Reduced latency mode" in the client properties (experimental in 1.9.7). |
| Authentication failed | Mismatched password or username | Technicians: regenerate access password on server. Customers: copy-paste exactly (case-sensitive). | Understanding the Customer Module is best done through
The technician copies needed files, prints a test page, or updates firmware on the remote USB device. All actions appear seamless.
IT technicians rarely have time for user-guided installations. The USB Redirector Client v1.9.7 MSI installer supports command-line switches (/quiet, /norestart). You can push this module via Group Policy, SCCM, or remote desktop tools without interrupting the customer. Even with stable software, network variables cause friction
A customer buys CAD software that requires a physical USB dongle (e.g., Sentinel or HASP). The dongle is at HQ. The remote engineer needs to run the software at home.
Technicians who have used prior versions (e.g., 1.8.x or early 1.9.x) will appreciate several refinements in version 1.9.7: Even with stable software
| Feature | Previous Version (e.g., 1.8.5) | Version 1.9.7 | | :--- | :--- | :--- | | Driver Installation | Often required admin rights and a reboot for first use. | On-the-fly driver loading; no reboot needed for 90% of generic USB devices. | | Customer UI | Basic list; easy to share wrong device. | Color-coded device types, confirmation dialog before sharing. | | Session Persistence | Connection loss required manual restart. | Automatic link recovery up to 60 seconds. | | Windows 11 Support | Partial, occasional crashes. | Full compatibility (tested on 21H2 through 23H2). | | Logging | Minimal debug info. | Verbose logging option for troubleshooting (customer can enable without technical knowledge). |
