I have a built in card-reader, which is supposed to be USB2. It's connected directly to the motherboard, which allso supports USB2.

However, transfer is much slower with this cardreader, comparing to plugging the camera (Pentax *istDS) to a USB2 port on the the PC via cable.

Something must be wrong. Any hints will be apreciated.

Yours

Lars

Just because it says USB2 doesn't mean it's high speed:

'USB2 Full-Speed' supports 12 Mbps whilst 'USB2 High-Speed' supports 480 Mbps.

Hi,

just wondering how can a built-in device have a USB2 connector ?I thought the reason why the USB (or or firewire or serial)were developed is because these are intended for external devices and not for internal or built-in devices

yeah thats another shitty marketing buzz word for usb. Basicaly:

USB 2.0 FULL SPEED = USB 1.1 = CRAP

USB 2.0HIGH SPEED = USB2.0 = DAMN FAST



Id say thats the case with your reader. pop along to http://www.digiprintuk.comfor some proper usb 2.0 readers.

Thanks to all contributors for your clarifications.

Seems like I'm in the market for a new cardreader :sad:
