TK. Posted June 20, 2003 Author Report Posted June 20, 2003 Update: I've installed a new kernel and Alsa driver from this (nice!) site:http://ccrma-www.stanford.edu/planetccrma/software/system.html#kernelThe MBHP USB module will be regognized immediately by the kernel (Plug & Play without further installation :-)):MBHP USB Manufacturer: Thorsten Klose Speed: 12Mb/s (full) USB Version: 1.10 Device Class: 00(>ifc ) Device Subclass: 00 Device Protocol: 00 Maximum Default Endpoint Size: 64 Number of Configurations: 1 Vendor Id: ac89 Product Id: 8ef1 Revision Number: 0.01 Both MIDI OUTs (/dev/midi0 and /dev/midi1) are working okBoth MIDI INs are routed to /dev/midi0I will check if the MIDI IN problem can be fixed in the firmware or if the Linux driver needs an adaption.Best Regards, Thorsten.

TK. Posted June 20, 2003 Author Report Posted June 20, 2003 Ok, it was a firmware issue - now both IOs are working perfectly with Linux.For the records: in difference to the Microsoft driver, the Linux solution is multiclient cabaple and has no problems with long SysEx strings ;-)The new firmware can be found here:http://www.ucapps.de/mbhp/mbhp_usb_v1_1.zipBest Regards, Thorsten.

Guest maxxel Posted July 26, 2003 Report Posted July 26, 2003 Hello,i'm new here on forum, but i've been visiting this page a lot during last year (found this page, after started to develop midibox with atmel, well, it's kinda still in development phase, maybe i'll do atmel core module in the future, but that's another story for another place).well, to the subject:I have question around USB module. I'll certanly have make few of them and I'm wondering if anyone tried to stuff one or more modules into one case using USB Hub chips?How much would this effect the speed? (my answer: probably nothing because USB is far faster than MIDI).maxxelp.s.: really great work TK! Quote
TK. Posted July 27, 2003 Author Report Posted July 27, 2003 I've 3 MBHP_USB modules running on a USB hub and no idea how to measure the additional latency. I guess that it is ignorable compared to the delay caused by the USB midi protocol itself (1 ms).Best Regards, Thorsten. Quote
pay_c Posted July 27, 2003 Report Posted July 27, 2003 How do you give those 3 devices different names? Or is that automatically done by Windows?Is it just "Audiogerät [number]" ? How can you differ between them? Quote
TK. Posted July 27, 2003 Author Report Posted July 27, 2003 They appear as "Audiodevice 1", "Audiodevice 2", "Audiodevice[2] 1", "Audiodevice[2] 2", ... etc.Best Regards, Thorsten. Quote
