...added ability to do subdriver-specific > initialization, and moved some shared code to agiler init function > since krauler doesn't need it. [...] I'm not very thrilled about this patch: 1) Down at the subdriver level, one shouldn't use ser_get_line() anymore, but usb->get_interrupt() instead or alternatively, get_data_agiler(). Hopping back-and-forth between various layers in the code is bad coding style as it makes the code difficult to understand. 2) So what is the benefit of this patch? It seem to try to optimize something away that complicates the subdrivers and really p...

...in that sense. To be more specific: In order to communicate with this UPS both input and output have to be performed as USB interrupts I/O as this UPS doesn't recognizes Control IO, so libusb_get_report() and libusb_set_report() will not work. Looking at libusb.c I realized there's a libusb_get_interrupt() which can be used to read from the endpoint, however there's no counterpart libusb_set_interrupt() API and usb_communication_subdriver_t structure doesn't contain a *set_interrupt element as well: libusb.h .... typedef struct usb_communication_subdriver_s { char *name;...

Hi! I've (finally) decided to try and make my PowerWalker work with megatec_usb. So far it seems the agiler subdriver is the way to go, but it doesn't work. The initial detection process sometimes succeeds in 1 out of 5 "Q1" commands, but that's about it (which is better than what the krauler subdriver can do... absolutely nothing). So, what needs to be done to obtain more
