 this should be in milliseconds. So it's 5s ....
 
 Now to find where the value comes from.
 You could print the first few bytes of xs->cmd to make sure it's a ERASE
 command. Then add prints from ADAPTER_REQ_RUN_XFER to check the timeout
 value when this command is sent to the adapter.
 Eventuelly add a Debugger() call and get a stack trace to see the code
 path that gets there and find where the timeout value is altered.
