Hallo Dan,
my usb programm with javax.usb runs gut in my Suse 8.0,
thank you very much Dan!
But after i installed the new Suse 9.0 last week, i have some Problems:
1. with fstab.
after i change the row of "usbdevfs /proc/bus/usb/ usbdevfs noauto 0
0"
to "usbdevfs /proc/bus/usb/ usbdevfs defaults,devmod=0666 0 0",
it comes "UsbException: Error Submitting IRP: Error -90" with CtrlIrp.
2. Instead of changing the fstab, I do it manually with chmod,
this time such Exception doesn't come further, but it seems
that the javax.usb runs not so stable,
program returns very frequently another UsbException:
"Error Submitting IRP: Submission aborted",
simplest command works sometimes still ok, but with a little
complicated tasks, like data transfering, work simply not right.
What is the problem ? I haven't a clue, from hotplugging?
Have you some tips?
in Suse 9.0:
Kernel 2.4.21, gcc 3.3.1, Java1.4.2
Thanks!
Chuan Guo
ps:
another problem, but not so urgent.
my external UsbHub (with self power) can result always to fail the whole
javax.usb, With it the javax.usb simply cannot runs.
Have someone such experience too?
