Hi, I made a reboot of the usrp e110. I got on the screen a button login. But I’m unable to login with a mouse. In fact, the mouse doesn’t work on usrp. But the mouse works well on my laptop. In fact, I even connected the mouse directly to a usrp e100 with a cable which is provided by Ettus(on host port). According to you what can be the problem ? Best regards, Wafa HAJ HMIDA ---

For a guide on how to get better help read this: [How To Ask Questions The Smart Way](http://www.catb.org/esr/faqs/smart-questions.html) . I would especially like to point you to “Choose your forum carefully” where this particular email violates at least 3 (and possibly 4 based on perspective) of the first 4 bullet points. There’s no need for this to be cross-listed to 3 mailing lists, a corporate support account, and 2 individuals. Also, this e-mail has nothing to do with GNU Radio. Second, I have no idea why your mouse doesn’t work. If it used to work, you did something, and now it doesn’t work then whatever you did probably had a side affect of breaking your mouse. Finally, based on your previous mailing list posts and irc chats you seem overwhelmed. My only real comment here is that you probably need more help/support than anyone can give over a mailing list. Perhaps you would be better off backing up from your final goal and learning more about GNU Radio on a standard PC and then try porting your work to an embedded device. Alternatively maybe you could also take some time to learn more about embedded systems (there’s lots of classes on-line and every university should have a couple). It might also help if you hired someone to come in and do some work for you and you could learn from them on the job. Nathan ---

Wafa, Try using a USB hub for the mouse instead of plugging it directly into the E100. E100 is picky about USB and doesn’t support USB1.1 devices directly connected to the ports. This is a Linux HCI driver issue related to OTG support in the Overo. It’s mentioned in the E100 FAQ: [http://code.ettus.com/redmine/ettus/projects/usrpe1xx/wiki/FAQ#What-kind-of-USB-devices-can-I-connect-to-the-my-E1x0-series](http://code.ettus.com/redmine/ettus/projects/usrpe1xx/wiki/FAQ#What-kind-of-USB-devices-can-I-connect-to-the-my-E1x0-series) –n On Wed, May 28, 2014 at 6:43 AM, West, Nathan ---

thank you, In fact, it works on OTG usb port. Best regards, Wafa HAJ HMIDA 2014-05-28 17:46 GMT+02:00 Nick F. [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid):
