[Feel free to point me to another mailing list if more appropriate] Hi! I am trying (as others tried to) to connect a Sony Cli? (PEG-SJ33) using uvisor. I built a 4.9-Stable kernel adding the following modules: # USB com devices device ucom device uplcom device uvscom device uvisor device uftdi I have actived USB_DEBUG and get the following trace when trying the hotsync: ucom0: Sony Palm Handheld, rev 1.10/1.00, addr 2 ucom0: Sony Palm Handheld, rev 1.10/1.00, addr 2 uvisor_init: getting connection info ucom0: Number of ports: 2 ucom0: port 1, is for Generic ucom0: port 2, is for HotSync uvisor_init: getting available bytes ucom0: init failed, IOERROR uvisor_attach: ATTACH ERROR device_probe_and_attach: ucom0 attach returned 6 usbd_transfer_cb: short transfer 2<9 uhub_explore: usb_new_device failed, error=SHORT_XFER uhub0: device problem, disabling port 1 I do not know the protocol and I am trying to understand what happen but if someone could explain me what is wrong, that'd be more than welcomed ;) Thanks a lot. Phil.
