Important:
If you're having trouble with USB ActiveSync, this utility may help you in certain situations. However, it is intended to be used after you have consulted your IT helpdesk or a PC expert. Do not run this utility without reading all information below and verifying that it fits your needs.
What does it do?
The USBSwitch utility is a workaround that lets you connect through a method other than RNDISยน. This is useful if your Windows PC configuration uses third-party software or network configurations that interfere with ActiveSync's ability to connect via RNDIS. RNDIS is capable of working correctly if the settings are properly configured, but some of these settings may be configurable only by your organization's IT Helpdesk.
Conditions that may prevent your RNDIS implementation from working include:
- VPN policy settings that prevent multiple network connections.
- Network policies that change NDIS settings.
- Firewalls that block ports and have not been updated to include ActiveSync in their exception list.
- Network optimization utilities on some laptops.
When RNDIS issues prevent synchronization, the USBSwitch Serial Switchback Utility may resolve the issue.
1 - See:
RNDIS info from Microsoft.com
Install and run the utility
Caution:
This utility should only be used for cases when the IT policy prevents the configuration of the Windows PC to allow ActiveSync to properly function. ActiveSync bandwidth and reliability may be affected when using this application.
