I tried the usual "fixes", such as uninstalling/reinstalling the USB controllers/device drivers.
In desperation, I tried a repair install of W10 Pro.
The printer in question is a brand new Ricoh SP-C250DN, which operated perfectly when I first plugged it in and selected USB for the initial installation of the drivers. However, after I tested the wireless functionality thru my router, I couldn't use the printer on USB anymore.
I was seeing "Copy 1" of the printer when I tried to get it installed for USB again. In an attempt to rid the pc of all things Ricoh so that I could reinstall and hopefully get it working on USB again, I removed both original and "Copy 1" of the Ricoh printer. That didn't get 'er done, so I deleted Ricoh reg entries -- the only Ricoh product that has ever been on this pc is this printer, so I felt safe in deleting these (I did not delete entries which contained non-Ricoh data).
I've done plenty of work in Windows registries over the decades, with few adverse incidents, but this time I obviously slipped up. I discovered the USB Printer Support is AWOL in Device Manager (yes, I set View to Show hidden devices) and USB001 Virtual Port is AWOL from the Add Printer port list.
Ok, so the reg is/was apparently FUBAR where USB is concerned, which is why I tried the repair install.
What I tried before the repair install:
- Ensure the USB connection in printer settings (front panel menu) is active.
- Connected printer to same USB ports that other devices do work with.
- Installed latest AS Rock drivers (mobo is FM2A85X Extreme6).
- Made certain USB is setup properly in BIOS.
- Confirmed usbprint and usbport inf and sys files are present and accounted for.
- Manually installed said inf's.
- Ran DISM scan, which reported perfect health.
Despite the repair effort, Windows can't see the printer and I'm therefore unable to get it installed for USB. I find it difficult to believe the printer itself suffered a coincidentally catastrophic failure in its USB circuits, but I suppose it's possible. I haven't tried another USB printer to rule that out.
From what I've read about USB Printer Support and USB001 Virtual Port, they supposedly only show up after printer drivers are installed. Therein lies the rub: I can't install the drivers because they want a USB local port selected to proceed with USB installation -- there isn't one and I can't add one (yes, I tried adding it manually). I'm wondering whether installing a different USB printer would bring them back, thus allowing installation of the Ricoh drivers.
Let's say that doesn't work. How do I restore USB Printer Support and USB001 Virtual Port without a full/virgin or reset install of W10 Pro?? I'm stumped and getting desperate for answers, but I'm not sure I'm that desperate, since I can use the printer wirelessly if I absolutely must.
P.S. This got moved to networking, but it probably belongs more in the driver subforum instead, since I'm not attempting to network the printer or share it, only use it as a USB printer. The router connection was just for testing the wireless connectivity (and that worked).
