		+	== 0.09 Updates ==
		+	I've been working on version 0.09 of usb8x. The version in the CVS is relatively stable, but I'll be posting an official release sometime soon. A couple things to mention:
		+	* In case anyone was wondering, the hardware allows you to setup the same pipe/endpoint number for both IN and OUT transfer.
		+	* The issue with a lot of flash drives not working (i.e. sandisk cruzer) was a bug in usb8x caused by #1. It's been fixed.
		+	* The new version includes a compile-time option for logging lots of internal state data to one of the extra RAM pages. Hopefully this will be useful for debugging new drivers.

	The state diagram is very nice. Unfortunately I wasn't able to map what I read in the diagram to what I saw going on on the 84P. So instead I took a little break from the research stuff and worked some more on the driver today. I got bulk I/O working, and wrote another demo: this time with the silverlink. In case anyone had been sitting up at night wondering, using the standard TI serial routines, the calculator can transmit data to itself at ~2.3 KB/s. --[[User:Dan Englender\|Dan Englender]] 23:25, 11 Jul 2005 (PDT)		The state diagram is very nice.

-**Same on Titanium but for device E00E. Some pieces of code check if this port has a value of 1: trap #4 (the hardware trap to shutdown the calc), the high-level function called "USBCheckReceived" by Kevin Kolfer used during file transfers (it quits if it is 1: no transfers if we are configured to used the adapter), the ROM Call EV_getc (which calls a routine that checks if the device has been unplugged, with 56:5), and the USB interrupt, which calls the same routine as EV_getc instead of the standard handler.

 ...These lower ports are especially odd because many of them are used very few times, or just once, in the OS.  Does the 89T have anything that might resemble these?  --[[User:Dan Englender|Dan Englender]] 00:52, 10 Jul 2005 (PDT)

 :I have thought about this for a while, it would be really helpful to debug any USB-related software written. The problem is that nothing has been tested yet on a real Titanium (Romain LiÃ©vin was to bring his calc to me during his weekend in Paris, but it seems we have missed each other). There are also many other ports we have not yet thought about. Perhaps you should wait for more information and for the current details to be stabilized.<br>
