I'm not so sure there are any drivers available yet for the T-bolt.
Here's a method of getting HTCSync going, which cause Windows to recognize your device (thanks to AndroidCentral):
1. Connect your phone to your computer using the supplied USB cable.
2. On your phone’s Connect to PC screen, tap Disk drive, and then tap Done.
On your computer, the connected phone is recognized as a removable disk.
3. Navigate to the removable disk and open it.
4. Copy HTCSync.exe to your computer.
5. After copying, unmount the removable disk (that is, the connected phone) as required by your computer’s operating system to safely remove your phone.
6. On your computer, double-click HTCSync.exe and follow the onscreen instructions to install HTC Sync.
After installing HTC Sync, the HTC Sync icon is added to your computer’s system tray (check the bottom-right side of your computer screen). You can double-click this icon to open HTC Sync.
Next:
1. Connect your phone to your computer using the supplied USB cable.
2. On your phone’s Connect to PC screen, tap HTC Sync, and then tap Done.
On your computer, wait for HTC Sync to recognize your phone.
3. When the Device setup screen opens, enter a name for your phone, and then click Save.
