Connect the hub to the external powercord. Sometimes it is not recognized because the hub cannot drain enough energy from the port.
if you are using a desktop pc, make sure it is plugged in the rear usb ports and not at the ones up front.

No you don't. Just plug it in to a USB 2.0 port on your PC and it should find it all by itself. You make have a problem if you are plugging a USB 2.0 hub into a USB 1.1 port. Also, you may well want to use the external power supply as it may not be able to draw enough power from PC USB port.

Unfortunately, Dynex no longer provides driver updates for their 1.3MP webcam on Windows 7 as the product has reached its end of life and is no longer supported. However, you may still be able to use the webcam with the existing drivers that came with it or with the generic drivers that are built into Windows 7. To check if your webcam is recognized by Windows 7, follow these steps:

1. Plug in your Dynex 1.3MP webcam to your computer's USB port.
2. Click on the "Start" menu and select "Control Panel".
3. Click on "Hardware and Sound" and then select "Device Manager".
4. Look for the Dynex webcam under the "Imaging devices" or "Cameras" category. If it is listed, then your webcam is recognized by Windows 7.

If your webcam is not recognized by Windows 7 or is not functioning properly, you may want to try downloading and installing a third-party driver update software like Driver Booster or Driver Easy. These programs scan your computer for outdated or missing drivers and automatically download and install the latest versions for you. Alternatively, you can try searching for a compatible driver on third-party driver download sites, but be cautious as some of these sites may contain malicious software. It is always recommended to download drivers from the manufacturer's website or from trusted sources.

Hi Jim, Some psu manufactures put a plastic sleeve over high voltage components as a safety measure. Is the piece you have flat or tubular?

Plug the keyboard into another device and if it works, then your Chrome laptop is at fault. If the keyboard does not work in a different device, toss it and buy another one, unless it's new, then take it back to the store where you bought it.

This sounds like you need a smartcard or your current smartcard is not working anymore. Your local provider probably "scrambles" the service over the line and you need to buy a certain subscription to see this channel. Please get in contact with your cable provider.

The Dynex DX-PWLMSE uses a 27 MHz frequency wireless connection between the mouse and a specific USB receiver. For the specifications, see https://www.dynexproducts.com/pdp/DX-PWLMSE/8632063 . To use the mouse, you need to press the Eject button behind the scroll wheel. This lets you open the battery/USB storage compartment. Put two AAA batteries into the mouse. Then remove the USB adapter (it's between the two battery slots). Close the storage compartment and put the USB adapter into an available USB 2.0 slot on the computer with a version of the Windows OS above Windows 98. (Note: the specifications I see indicate Dynex wrote drivers for Windows Vista. It may not work with Windows 7, 8 or 10.) Make sure that the computer is on and can get driver updates from on-line sources. Turn on the mouse and it should auto-pair with the receiver. If there is no response, try pressing and holding the connect button on the bottom of the mouse. I'm not aware of any vendors that sell the USB receiver for this mouse. The manual for the DX-PWLMSE is available from Manuals Lib: https://www.manualslib.com/products/Dynex-Dx-Pwlmse-Wireless-Optical-Usb-Laptop-Mouse-4908.html . I hope this helps. Cindy Wells
