Hi Everyone, Yet another USB dilemna with the TMS320VC5509. I am currently using the USB Driver from DDK 1.1 and I am having problems getting the USB device to reconnected if I unplug and replug the USB cable. Basically, if I unplug the USB cable I can't get it to communicate again after I replug it again. Before I really get down to the nitty gritty, I was wondering if someone else had success with modifying the USB Driver from DDK 1.1 or if I should just rewrite it all over again for myself. Thanks in advance for all your comments! Sylvio |

That DDK stuff was a pile of junk. Just use the native CSL USB methods and they work much better. I can connect/disconnect and never have a problem. Make sure you run the CPU clock at least 48MHz. If it runs slower than 48MHz it can miss interrupts and cause USB problems. Other than that, it seems to work pretty well.
