Among other things, this can cause slow access as the BIOS may use USB1 speeds for USB2 devices. <br \/><br \/><\/li>\r\n    <li>If you have multiple USB controllers, you may connect the USB input device(s) and drive to different controllers and use the <strong>USBIgnoreMask<\/strong> option to hide one of them from BootIt BM.&nbsp; By hiding the USB controller where&nbsp;the USB&nbsp;input device&nbsp;is plugged in, you can prevent BootIt BM from taking control of&nbsp;the USB&nbsp;input device&nbsp;and therefore prevent BootIt BM from interferring with it.&nbsp; (If you don't already have an alternate USB controller available, one option is to obtain and install a PCI-based USB controller.)&nbsp;It usually takes some experimentation to determine which controller to hide, but the two USB ports next to each other are usually controlled by the same host controller. <br \/><br \/>To access the <strong>USBIgnoreMask<\/strong>&nbsp;option it is necessry to edit he BOOTITBM.INI file located in the BootIt&nbsp;EMBRM partition. In Work with Partitions, select the BootIt EMBRM partition and click the <strong>Edit File<\/strong> button. Select the BOOTITBM.INI file and click <strong>OK<\/strong>. Locate the <strong>[Options]<\/strong> section and create a new line in it for the <strong>USBIgnoreMask<\/strong> option. Set the value depending on the controller(s) you wish to ignore and then click <strong>OK<\/strong> to save the file. For example:<br \/><br \/>To hide the first controller: <strong>USBIgnoreMask=1<br \/><\/strong>To hide the second controller: <strong>USBIgnoreMask=2<br \/><\/strong>To hide the third controller: <strong>USBIgnoreMask=4<br \/><\/strong>To hide both the first and second controllers: <strong>USBIgnoreMask=3<br \/><\/strong><br \/>Note that the <strong>USBIgnoreMask<\/strong> option uses a basic Bit Mask numbering scheme to select the controller(s). <br \/><br \/>If this option&nbsp;does not provide a successful workaround to the issue, edit the BOOTITBM.INI file again and undo the changes.<br \/><\/li>\r\n  <\/ul>","protected":false},"excerpt":{"rendered":"<p>Problem:Your USB input device (keyboard or mouse)&nbsp;stops responding after selecting USB in the Bus drop-down&nbsp;in Work with Partitions.Cause:When BootIt BM takes control of a USB controller, it only provides support for mass storage devices.Solution:You may try the following suggestions: Use a PS\/2 input device, either at all times, or only when using BootIt BM.
