Force USB Device Discovery in Ubuntu

3 Replies

I previously did a post on how to Create a Button to Restart USB in Ubuntu. The purpose of that procedure was to get the USB hub in my HP w2207 monitor to recognize a flash drive that had been inserted into one of the ports.

Well I’ve found a better way to force this recognition that doesn’t require root permission. It turns out that issuing the lsusb command polls all of the USB devices and causes my flash drive to be recognized and automounted. You can try this in a terminal with: Continue reading →

Update: Logitech LX8 in Ubuntu

2 Replies

I first wrote about the Logitech LX8 back in August, 2008. The one feature that had eluded me was the side scrolling with the tilt wheel. Through some information I found on fellow blogger Ken Zutter’s site, I now have my LX8 working in Ubuntu including the side scrolling feature. The key was to go back to the evdev driver.

No changes in button mapping in the xorg.conf file made a difference, so I resolved to make the mapping changes with Xmodmap.

I’ve been using my HP w2207 flat panel monitor for some time now. My only frustration has been that I haven’t been able to get the USB ports on the side to work unless I have a device plugged in when the computer boots. I think this is more the fault of Ubuntu than it is the monitor. Ubuntu just doesn’t seem to care about a USB hub unless there is a device plugged into it. After a little searching on the web I found that a fellow blogger had posted a solution on Hack 2 Live. Continue reading →

How to resample MP3 audio files on Linux using LAME

If you’re like me, you’re not willing to shell out several hundred dollars to buy an 80GB iPOD to carry and store your music collection. In my case, I chose the 4GB Sansa e260 as my music player. Having ripped my music at high bitrates for improved quality, I soon became dissatisfied with the capacity of my player. At that point, I decided to do some experimenting with LAME‘s different encoding options in order to determine what settings gave me the minimum file size while providing acceptable sound quality. For me, LAME’s variable bit rate preset 5 provides a good compromise between sound quality and file size. Continue reading →
