SmartRF06EB USB drivers fail to install on W7

Other Parts Discussed in Thread: CC2531, UNIFLASH

Hi,

We have purchased the CC2538DK (2 x SmartRF06EB + 2 x CC2538EM + CC2531 USB dongle). On most of our PCs (W7 Pro 64), the SmartRF06EB + CC2538EM work fine once connected through USB (XDS100v3). However, for one of our PCs, Windows fails to install the driver, saying that it can't find any.

The device is properly recognized by Windows (USB vendor and product IDs, and name), but Windows refuses to use the drivers installed from TI's applications. All TI applications have been uninstalled from this PC, then the latest versions of the following TI applications have been installed before connecting the device: CCS, CCS UniFlash, SmartRF Programmer, SmartRF Packet Sniffer and SmarRT Studio.

All the troubleshooting guides from your Wiki and your documentation fail.

If using a VMware guest operating system (tested with Ubuntu and XP) on this machine (W7 host), then the device is installed properly on the guest operating system, so this is not a hardware issue. However, there are other issues with these tools running in these virtual machines that prevent it to be a valid workaround.

I have noticed that when connected to the host W7 on this PC, the POWER LED on the SmartRF06EB is not turned on, as if W7 were maintaining the USB device unconfigured or suspended, which then prevents the install procedure from succeeding.

Hi,

What is the serial number of the failing SmartRF06EB? You say the device is properly recognized by Windows - what do you see in the Device Manager? Does the user have administrator privileges?

Hi,

The serial number of the failing SmartRF06EB is 0x00425. The serial number of the CC2538EM connected to it is 0000 05FB. Note that these boards work if connected to some PCs.

You will find in the attachment a screenshot of what I see in the device manager, and the output of USBView.

Yes, the user has administrator privileges.

Hi,

Please find attached the USB ETW event trace corresponding to when the board is plugged in. See http://msdn.microsoft.com/en-us/library/windows/hardware/jj151577%28v=vs.85%29.aspx .

We also have a Vista PC with the same issue.

Hi,

It may be an issue with the VID/PID on the computers you mention. Try running FTDI's "CDM Uninstaller", found at http://www.ftdichip.com/Support/Utilities.htm. It will delete registry and drivers for the PID/VID specified.

Let's hope this helps.

Hi,

Sorry, but it does not help.

I have tried with other products using FTDI chips. All single-channel (e.g. FT232R-based) devices that I've tested work fine while all dual-channel (e.g. FT2232H-based) devices exhibited the same issue.

Hi,

I've found the root cause of this issue. For some reason, C:\Windows\inf\usb.inf and C:\Windows\inf\usb.pnf were missing. I have restored them from the Windows DVD, and then everything worked fine.

Best regards,
Benoît

I'm glad to hear that you found the root cause, I'm sure other's will benefit from this.

Thanks for sharing your solution!
