Don\u00b4t try to redirect a device that require 36mbit\/s\u00a0\/ 4,5mbit\/s (Blue Ray Burner single speed) thru a 2mbit WAN connection&#8230; It will not work stable.<\/p>\n<p>2) Voltage: If using an old USB Harddisk, use the right cable (Y-cable if needed) and make sure that the USB port can deliver the required\u00a0voltage or use an active USB Hub with a seperate power supply. If you&#8217;re using a thin client which is a low voltage device, check this out first! Also do not use USB christmas gimmicks or USB coffee cup heater together with a thin client or any other low voltage device (tablet computer\/netbook). Low voltage devices in general don&#8217;t provide a 450w power supply\u00a0which is able to compensate this..<\/p>\n<p>3) USB devices mostly require a &#8220;stable&#8221; network connection to be redirected, if this is not available.. Be prepared to have some fun with the users!<\/p>\n<p>4) A USB device\u00a0which\u00a0is redirected to a virtual desktop or somewhere else\u00a0can not be used with the local OS, this applies especially for keyboards, USB network devices and similar. Redirecting a USB WiFi device is a bad idea if you\u00b4re using this device also for the local network connection (connections loss after connection to the VM is established), redirecting a keyboard is a bad idea if you want to use it local (alt+ctrl+del as sample will be processed only in the VM and not at the end user\u00a0device).<\/p>\n<p>5) For IGEL devices: Enabling USB redirection in general will not redirect all connected usb devices, you have to allow it seperatly by class or device id\u00a0to prevent issues mentioned in 4).<\/p>\n<p>Cheers<\/p>\n<p>Michael<\/p>\n<p>P.S.: A small extension&#8230; Try to use &#8220;real&#8221; USB redirection only if you&#8217;re really need it! Very often there are more effective ways to use a USB device in a remote session thru virtual protocol channels like for audio devices, memory sticks, printers\u00a0or smart card readers.<\/p>\n\n<div style=\"font-size: 0px; height: 0px; line-height: 0px; margin: 0; padding: 0; clear: both;\"><\/div>","protected":false},"excerpt":{"rendered":"<p>Hello folks, very often users blame that &#8220;real&#8221;\u00a0USB redirection doesn&#8217;t work well and they\u00b4re running in serveral issues.
