The logs there appear not to have debugging enabled in usb-serial core. Please post the logs with debugging enabled in both modules to this thread as well.
O.K. Nobody has requested this so far. So this time with both modules in debug-mode: root@PC:# lsmod | grep usb usb_storage 43870 0 usbserial 32061 1 pl2303 usbhid 36379 0 hid 81288 1 usbhid usbcore 128498 8 ehci_hcd,ohci_hcd,usbhid,usbserial,uas,usb_storage,pl2303 usb_common 12354 1 usbcore scsi_mod 162372 6 libata,sd_mod,sr_mod,sg,uas,usb_storage root@PC:# rmmod pl2303 root@PC:# rmmod usbserial root@PC:# modprobe usbserial debug=1 root@PC:# modprobe pl2303 debug=1 * Then i connected the adapter. * Connect with cutecom and a wired loop with 9600 baud. * Write "Test" * Close connection * Remove adapter Logs attached.
Is write also broken by the way?No - that works perfect everywhere.And you said you had verified that there was data on the wire when read fails?
Yes - there was a microcontroller connected that sends simple counter data every second.
Thanks, Johan
