NEC PCI to USB Open Host Controller -- Code 38 after waking up from stand-by/sleep

    Question

  • I use a Dell E6400 laptop with Windows 7 64-bit. I have a cellular card that I use with the laptop for connectivity on the go.

    Within the last month or so, I've noticed that now almost every time the laptop comes out of sleep mode, the wireless card is not found. Digging further, I noticed that when this happens, there are two "NEC PCI to USB Open Host Controller" devices in Device Manager with Code 38 (already loaded). When everything works, the first one of these is the device that controls the card in question.

    I've no idea what caused this to start behaving badly -- perhaps a Windows update.

    But in any case, I need to find a solution. Any ideas? The drivers for "NEC PCI to USB Open Host Controller" are from Microsoft and appear to be the latest version. I believe they are for the PCMCIA cards to be used at all. I have tried updating the Ricoh PCMCIA card drivers from Dell, but that doesn't seem to make a difference at all, although that device is also there and does not show any errors.

  • Well, I uninstalled VMWare and confirmed that the problem went away. So I guess its a problem with VMWare. Now if only Virtual PC could handle 64-bit guests and multiple processors I wouldn't need VMWare.

  • This is not a machine / hardware / BIOS problem. I've had the machine since October and use sleep multiple times a day without any issues. This problem only recently started occuring.

    I spent some time with Event Viewer and did some other hunting around. The problem started around 4/19, right after I installed VMWare Player. More research reveals other users have had similar problem with other VMWare products. I have posted on their forums in the hopes of finding a solution (other than uninstalling VMWare Player).
