PCAN-USB, PCAN-USB ISO, and PCAN-USB Pro adapters connected through USB 3.0 depend on the PC BIOS, USB 3.0 host-controller driver, and associated controller firmware. The available evidence attributes connection problems to older USB 3.0 software, but it does not identify a CAN-driver error code or a specific failure symptom.
Identify the USB 3.0 controller
Determine which USB 3.0 host controller the PC uses before selecting an update. The evidence distinguishes Renesas, Intel xHCI, ASMedia, Fresco Logic, Texas Instruments, Etron, and VIA controllers; a driver for one controller family is not evidence of compatibility with another.
Interpret the recorded driver versions
These versions are historical reference points from the supplied evidence, not current recommendations. The source identifies Renesas version 2.1.19 as current on 21 July 2011, while a later continuation lists version 2.1.39.0 for the same controller family.
| USB 3.0 controller | Version recorded in evidence | Qualification stated |
|---|---|---|
| Renesas uPD720200 / uPD720200A | 2.1.39.0 | Not stated |
| Renesas uPD720201 / uPD720202 | 3.0.23.0 | WHQ |
| Intel xHCI, 7-series chipset boards | 1.0.8.251 | Not stated |
| Intel xHCI, 8-series chipset boards | 2.0.0.102 | Not stated |
| ASMedia | 1.16.2.0 | Not stated |
| Fresco Logic | 3.5.93.0 | WHQL |
| Texas Instruments | 1.16.2.0 | WHQL |
| Etron | 1.0.0.0115 | Not stated |
| VIA | 6.1.7600.3105 | WHQL |
Update the USB 3.0 path
- Identify the PC motherboard and installed USB 3.0 controller.
- Install the newest BIOS approved for that PC or motherboard.
- Obtain the newest applicable USB 3.0 host-controller driver. Check the PC manufacturer first; if its package is outdated, compare it with the chipset manufacturer's release.
- Update the USB 3.0 controller firmware when the selected package or manufacturer procedure includes it.
- Reconnect the PCAN-USB, PCAN-USB ISO, or PCAN-USB Pro to the USB 3.0 port and repeat the operation that previously failed.
Verify the result
Confirm that the installed driver belongs to the detected controller family and that the adapter remains connected during the required CAN operation. If the failure persists, record the controller model, BIOS revision, installed USB 3.0 driver version, firmware version, adapter model, and observed symptom. The evidence does not establish that any listed historical version resolves every USB 3.0 compatibility problem.
FAQ
Why does my PCAN-USB adapter fail on a USB 3.0 port?
The supplied evidence identifies outdated BIOS, USB 3.0 host-controller drivers, and controller firmware as areas to check. Update the components applicable to the PC, then reconnect the adapter and repeat the failed operation.
Which USB 3.0 driver should I install for PCAN-USB?
Install the driver for the PC's actual USB 3.0 controller. Identify whether it is Renesas, Intel xHCI, ASMedia, Fresco Logic, Texas Instruments, Etron, VIA, or another controller before selecting a package.
Is Renesas USB 3.0 driver 2.1.19 still the required version?
No current requirement is established by the evidence. Version 2.1.19 was identified as current on 21 July 2011, and a later evidence entry lists 2.1.39.0 for Renesas uPD720200 and uPD720200A controllers.
