    <p>I remember reading some books about Linux Device drivers around the end of my university education for Comp. Science. Soon there-after I got a job and haven't really worked much with Linux/Embedded (I do mostly java stuff now). However it's something I want to look into.</p> <p>Anyways I recall reading an online article (ill edit post if I can find it) about writing a USB Driver for Linux for a Little "USB Missile Turret" similar to this: <a href="http://www.thinkgeek.com/geektoys/warfare/8a0f/" rel="nofollow">http://www.thinkgeek.com/geektoys/warfare/8a0f/</a></p> <p>Anyways it went into detail about how to write the driver without a driver being provided (the guy just found a generic one on ebay....and figured out how to like...write the driver just by looking at the components and such). ANYWAYS it was pretty amazing.</p> <p>I have a pretty good clue about how low level embedded stuff works, but thats for stuff like AVR's/PIC Microcontrollers, I have no idea how something like this would be written for like a Normal processor in a PC.</p> <p>Anyways I guess what Im asking is.....how do you figure out this kinda stuff, where would I find such information.</p> <p>edit: found the link <a href="http://matthias.vallentin.net/blog/2007/04/writing-a-linux-kernel-driver-for-an-unknown-usb-device/" rel="nofollow">http://matthias.vallentin.net/blog/2007/04/writing-a-linux-kernel-driver-for-an-unknown-usb-device/</a></p> <p>(It's way more confusing then I thought, I didn't realize he reverse engineered a Windows USB driver..im guessing it'd be impossible to figure out without snooping through a windows driver?)</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
