|I've seen that when some USB 2.0 devices are connected to USB 1.x ports. The message is probably generated either because of something in the printer's software, or something in the device driver(s) *.inf file for the device, that prefers you use a USB 2.0 rather than a USB 1.x connection.|
There might be a setting in the printer's software or Properties that allows you to disable that from happening, or something such as a blank square you see along with the message beside "Do not show me this message" or similar you can click on to insert a checkmark to enable, but sometimes there's nothing you can do about it.
There may be a way of disabling the message besides that, but I have not come across info about how to do that.
If your mboard has no USB 2.0 ports, of course, you could provide a USB 2.0 port for the device - if you have a desktop computer and get yourself a PCI USB 2.0 controller card (available for as little as $30 or less), or if you have a laptop get yourself a PCMCIA 2 or 4 port USB 2.0 controller card adapter (available cheaply), and connect the USB 2.0 device to that.
The USB 2.0 printer or printer/scanner/etc. will usually still work fine with a USB 1.x connection, except the USB 1.x max data rate is much less - printing or scanning will be slower.
If your printer or printer/scanner/etc. is/are not working properly otherwise that's another matter - it may not work properly connected to a USB hub -
See response 3 in this:
(common reasons you may have problems when you connect to certain USB ports, etc.)
- but connecting it to a USB 1.x port directly connected to your mboard, or to a USB 1.x controller card in a slot, will probably not get rid of the message you are getting.
