A reported Windows 7 Ultimate 64-bit installation ran Delta Tau PeWin Pro2 Suite v4.2.11.0 and communicated with a Geo Brick through USB, serial, and Ethernet. This is an observed configuration dated April 6, 2010—not an official compatibility statement. USB required repeated driver reinstalls before Windows recognized the controller correctly; serial and Ethernet worked without reported driver-recovery steps.
Tested configuration and results
| Component | Tested configuration | Observed result |
|---|---|---|
| Host | MacBook Pro, Boot Camp 3.1, Windows 7 Ultimate 64-bit | PeWin started successfully |
| Software | PeWin Pro2 Suite v4.2.11.0 | Installed without reported errors |
| USB | Geo Brick with DT64bitDrivers.zip | Failed initially; worked after repeated driver reinstalls |
| Serial | SIIG USB-to-serial adapter JU-CB1S12-S3, Hardware V3; SER3 on COM3 | Communication succeeded |
| Ethernet | New PMAC Ethernet device configured with the Brick IP address | Communication succeeded |
Recover the failed USB installation
The initial USB connection appeared in Device Manager as ACC54E USB device with no driver. Power-cycling the Brick, reconnecting USB, and removing the failed Device Manager entry did not resolve the problem by themselves.
- Install PeWin Pro2 Suite v4.2.11.0.
- Extract
DT64bitDrivers.zipand runsetup.exe. - If Device Manager shows
ACC54E USB devicewithout a driver, run the same setup program and select its uninstall option. - Run the driver setup again, reconnect or power-cycle the Brick, and check Device Manager.
- If recognition still fails, repeat the driver uninstall and reinstall. In the reported case, the driver became functional after three uninstall/reinstall attempts; the evidence does not establish why repetition fixed it or guarantee the same count elsewhere.
Verify the working state
Confirm that Device Manager contains a Motion Controllers group with Delta Tau UMAC USB 2.0 Device. Then start PeWin and verify live communication with the Brick. The reported working system also contained these driver files:
\Windows\System32\Drivers\PmacPCI.sys 44 KB 3/30/2009 2:37 PM
\Windows\System32\Drivers\pmacusb.sys 43 KB 3/30/2009 2:37 PMUse the Device Manager identity and successful controller communication as the primary acceptance checks. File presence alone does not prove that Windows associated the USB device with the correct driver.
Alternative communication paths
If USB remains unavailable, the tested alternatives were serial and Ethernet. For serial, Windows found the SIIG adapter driver, after which a new PMAC device was configured as SER3 on COM3. For Ethernet, a new PMAC Ethernet device was configured with the Brick's IP address. Both paths communicated successfully in the reported system, but the evidence does not define network settings beyond the controller IP address.
FAQ
Does Delta Tau PeWin Pro2 work on Windows 7 64-bit?
PeWin Pro2 Suite v4.2.11.0 was reported working on Windows 7 Ultimate 64-bit with a Geo Brick. The evidence does not include an official Windows 7 support statement, so treat this as a tested field configuration.
Why does the Geo Brick appear as ACC54E USB device with no driver?
That Device Manager entry indicates that the tested system had not associated the Brick with the Delta Tau USB driver. Uninstall and reinstall the package from DT64bitDrivers.zip, then verify that the device becomes Delta Tau UMAC USB 2.0 Device under Motion Controllers.
How do I verify the Delta Tau USB driver installed correctly?
Check for Delta Tau UMAC USB 2.0 Device under the Motion Controllers group, start PeWin, and confirm communication with the Brick. The reported installation also showed PmacPCI.sys and pmacusb.sys in \Windows\System32\Drivers.
