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.
Jun 27 14:19:21 localhost kernel:   Length              = 18
Jun 27 14:19:21 localhost kernel:   DescriptorType      = 01
Jun 27 14:19:21 localhost kernel:   USB version         = 1.10
Jun 27 14:19:21 localhost kernel:   Vendor:Product      = 13fa:5276
...
Jun 27 14:19:42 localhost kernel: usb.c: USB disconnect on device 83
Jun 27 14:19:42 localhost kernel: hub.c: USB new device connect on bus1/1,
assigned device number 84
==================

Any ideas?

Many thanks
