USB driver for RCA 7 Voyager rct6773W22 I can't seem to get my RCA rct6773W22 (7 Voyager) tablet to be detected via USB and RCA does not offer any driver.

If anyone has any idea how to fix this, I would greatly appreciate it.
This question was answered on this website. I will briefly summarize the steps I took to allow my RCA Voyager (RCT6873W42) running Marshmallow 6.0 to sync up with my Windows 7 computer and ADB in Android Studio. 
1. Install the Google USB drivers.
2. Find the device ID by navigating in Windows to (Control Panel)>(Device Manager)>(Other Devices)>(Android ADB Interface)>(right-click: Properties)>(tab: Details)>(‘Property’ drop-down: Hardware Ids) which yielded

USB\VID_8087&amp;PID_0928&amp;REV_FFFF&amp;MI_01
USB\VID_8087&amp;PID_0928&amp;MI_01

3. Open up C:\Users\Stewart\AppData\Local\Android\sdk\extras\google\usb_driver\android_winusb.inf in Notepad++ and add the following lines after both [Google.NTx86] and [Google.NTamd64]
;RCA Tablet RCT6873W42
%SingleAdbInterface% = USB_Install, USB\VID_8087&amp;PID_0928&amp;REV_FFFF&amp;MI_01
%SingleAdbInterface% = USB_Install, USB\VID_8087&amp;PID_0928&amp;MI_01
(Notice that you have appended the the device IDs you obtained in step 2 to the direction%SingleAdbInterface%=USB_Install,.)
4. After saving android_winusb.inf, navigate back to device manager, right-click on the unknown device (Android ADB Interface) and choose ‘Update Driver Software…’.
5. Choose Browse my computer for driver software: Locate and install driver software manually. Then choose (Browse), navigating to where the drivers are stored (C:\Users\Stewart\AppData\Local\Android\sdk\extras\google\usb_driver) and clicking (Ok).
6.  Make sure that the ‘Include subfolders’ option is checked and click (Next).
7. If you open up Android Studio with your device connected, it should now show up in the ADB after several seconds. 
Note: Some of these details may vary. The location of your SDK will undoubtedly be different. What you write in the .inf file comment is arbitrary. I chose to write ;RCA Tablet RCT6873W42. I assume you have enabled developer options on your device, allowing USB. You should be able to easily follow Google's direction on installing their USB drivers. An additional step was listed on the website (see above) which I did not have to follow.
