Hitch specification


Allow us to introduce you to Hitch.


The Hitch is a new product from Sima intended to, as we've already discussed, allow file transfer between USB devices without the need for a PC. The model we have here is the Hitch USB-101, the first of the Hitches, if you will. Here's a run-down on its official features and specification, as taken from

To summarise Hitch's specification, it can connect two USB devices together, providing they use the FAT filesystem or the Picture Transfer Protocol. The vast majority of USB devices that operate with a mass storage driver have a FAT-formatted filesystem. This includes thumb drives, memory cards (via a USB card reader), external hard drives and many cameras. Some cameras, while still operating on the FAT filesystem, interface with the host device using the Picture Transfer Protocol, rather than a mass storage driver, hence the PTP support.

USB 2.0 support suggests that we'll get nippy transfers from Hitch and seeing as 'up to 500mA at 5V' can be provided to each port, we shouldn't have any trouble with any device that draws power over USB, given that 500mA is also the current limit on a PC's USB implementation.

Enough talking around the specifications. Let's see what Hitch is really made of.
