USB Drive Requirements

The N300 wireless modem router works with 1.0 and 1.1 (USB Full Speed) and 2.0 (USB

High Speed) standards. The approximate USB bus speeds are shown in the following table.

Actual bus speeds can vary, depending on the CPU speed, memory, speed of the network,

and other variables.

The N300 wireless modem router should work with USB 2.0 or 1.1-compliant external flash

and hard drives. For the most up-to-date list of USB drives supported by the N300 wireless

modem router, go to:

When selecting a USB device, bear in mind the following:

•

The USB port on the N300 wireless modem router can be used with one USB hard drive

at a time. Do not attempt to use a USB hub attached to the USB port.

•

According to the USB 2.0 specification, the maximum available power is 5V @ 0.5A.

Some USB devices might exceed this requirement, in which case the device might not

function or might function erratically. Check the documentation for your USB device to be

sure.

•

File Sharing Scenarios

You can share files on the USB drive for a wide variety of business and recreational

purposes. The files can be any PC, Mac, or Linux file type including text files, Word,

PowerPoint, Excel, MP3, pictures, and multimedia. USB drive applications include:

•

Sharing multimedia with friends and family—sharing MP3 files, pictures, and other

multimedia with local and remote users.

•

Sharing resources on your network—storing files in a central location so that you do not

have to power up a computer to perform local sharing. In addition, you can share files

between Macintosh, Linux, and PC computers by using the USB drive as a go-between

the systems.

•

Sharing files with offsite coworkers—sharing files such as Word documents, PowerPoint

presentations, and text files with remote users. A few common uses are described in the
