Dear all my apologies for answering too quickly without doing my homework.
I double checked, and in fact, EP1 is an out endpoint (meaning from host to the device), while EP2 is an IN endpoint. This means that the behavior under Windows is correct. Any other ideas what could be wrong here? Another question: if kernel attach and detach only has effect in Linux, why does libusb_kernel_driver_active(handle,0) return true on Windows? Shouldn't it return false then? best regards Wim -----Original Message----- From: Xiaofan Chen [mailto:xiaof...@gmail.com] Sent: vrijdag 15 februari 2013 15:47 To: libusbx-devel@lists.sourceforge.net Subject: [SPAM] - Re: [Libusbx-devel] [SPAM] - Re: opening generic device EP in bulk transfer - difference between Linux and Windows - Email found in subject - Email found in subject - Email found in subject On Fri, Feb 15, 2013 at 10:21 PM, Xiaofan Chen <xiaof...@gmail.com> wrote: > On Fri, Feb 15, 2013 at 10:17 PM, Wim De Kimpe > <wim.deki...@medecbenelux.be> wrote: >> but on Windows, it does not work with nEndpoint = 0x81 > > You need to know your device better. Please post the output of "lsusb > -vvv" result of your device under Linux. You need to make sure whether it is true that "EP1 is in, EP2 is out". Take note that USB is host centric, the "IN" or "OUT" is from the host point of view.
