Hi all, I am trying to get a Cypress EZ-USB-FX based device working under linux and I am having some trouble.
1.) The device appears to be continuosly connecting/disconnecting. When device is plugged in, it is detected by the host driver and not claimed by any active driver (as expected). Then the hotplug tries to store the new firmware using fxload. But nothing happens. No reset after the storing process, but after a while (more or less every 20 s), the device is automatically disconnected and connected again starting other time the process. It seems the problem is not of hotplug because if I disable it, this strange "connection/disconnection" state is still happening Some system logs: ================= Jun 27 14:19:21 localhost kernel: hub.c: USB new device connect on bus1/1, assigned device number 83 Jun 27 14:19:21 localhost kernel: usb.c: USB device 83 (vend/prod 0x13fa/0x5276) is not claimed by any active driver.
