Usb host to host communication failure on WC7655

Re: Usb host to host communication failure on WC7655

The less problematic software version is 033.53180 SPAR
The last version is 53375 also SPAR.
Many problems comes from bad sectors on controller hdd's

Re: Usb host to host communication failure on WC7655

Ive resolved a dozen of these errors over the last few weeks.
almost all the cases resolved itself after getting a clean software install.

if there is a lot of controller swapping going on, or even controller part swapping, hdd mainly, the ess locks up and it does not seem to get free by itself again.

Ive had 1 or 2 cases were there was actually something wrong with the usb connection or cable too, so dont exclude it before hand.
Basically though, if the controller software is not functioning correctly you get a usb host to host error, the entire machine runs off the controller rather than just the network part.

i have software version 040.033.52800 which is by no means recent but it works, i can up a copy for you if you want. if you do find more recent software i'd love to be on the sharing list tho

I currently have the 'host to host' error.

This is how I got the error...
I've 2 7655 printers and one had the 'firewire communication error'. So i tried to put the controller from the second machine to see if it would work.
When it was booting up, I noticed that it started updating the printer but couldnt stop it as it warned me not to. It boot up fine and even printed..

So I decided to put the old controller back. It boot up fine but when I tried to send jobs, they were kept in 'pending' mode and wouldn't print!

What did I decide to do? swap the 2 hard disks and after that they wouldn't boot on both printers! even after putting them back.

I've the Pws and 040.033.5350 software but am not able to re-install since altboot is not able to see the controller booting up!

I've blown the controller, re-installed the dimms, hdd but altboot wont boot.

Diagnosis through the usb cable says that 'ess is not available' but prints test prints.

What am I doing wrong?

Re: Usb host to host communication failure on WC7655

Well im usually a big fan of imaging xerox discs and then writing out clones when one fails, usually much faster than re-installing with the cd's
In the case of the 7600 series all atempts of the sort have uterly failed, any attempt to swap an hdd to another controller resulted in the software corrupting.
i suspect that it detects some kind of bios id linked to an individual controller.

As for your current situation, what does the hex display on the back of your case say ? 00 / FF or something else? have you tried swapping your service switches?
Have you ever used your pws setup before? null modem serial cable / 7600 alt boot. so we can exclude that from being faulty.
Have you tried hooking up a normal monitor? iirc your able to see the post information normally, then it displays the booting linux kernel... if you get this far you can exlude post errors and likely most of your hardware is ok.
You can also use putty instead of altboot, saw a guide floating around on this forum somewhere, has the advantage you dont need gsn.

Let me know if you got your issue resolved

Reload SW and the BIOS using the Altboot. There will be a Load BIOS option. Make sure the ESS is disconnected from the Printer. After the reload connect as normal and let the ESS load the SW to the other components as it did before.

Re: Usb host to host communication failure on WC7655

Thanks for your reply.

There's no hex display as it is a 7655. I believe you find this from the 240 upwards.

I use the pws everyday on different machines and on this case I even used a new null modem.

I haven't used the monitor option(does it work on a 7655?)

Do you have the putty software?

Now a new development has come up.

I connected a new hdd and after putting back the old hard drive, the network port is no longer blinking. it does though on the second controller.

WARNING!!! Don't swap HDD on different controllers.. Its like corrupting its software.

So when am loading the software, the controller should not be connected to the printer? Should I power it independently or through the back to back power cables from the printer? what about the firewire and usb connection?

In this particular case you must think like a PC tech.
You have a PC computer with a nonbooting motherboard and must find the failed device.

Re: Usb host to host communication failure on WC7655

Don't ever swap controllers. The chances of you corrupting the hard drive are high and the software levels need to match

Re: Usb host to host communication failure on WC7655

Having the same problem but also getting a message unable to communicate with the remote xerox smart esolutions server !
I check the cables, reseated the memory the fan is operating. The machine takes forever to get to the ready screen and when it does and a copy is made it just says waiting to print! Why does xerox call it a firewire, when it's a usb, and could this problem be the usb cable between the machine and the fiery?

you should have both a firewire and a usb cable connected. the usb cable comes from the screen, and need to go in a specific slot of the 4 usb connections on the controller. The firewire cable is used between the controller and the printer.
The solution to most errors of this kind is reinstalling the software, like stated here a couple of times. 9/10 its software 1/10 is cables

Re: Usb host to host communication failure on WC7655

Hello 7600 series technicians,

I have a pws but I do not have the system software. I have a 7655 and a 7675 that have had the hdd wiped and probably replaced with hdd from different machines. I need to reinstall the software.
Can anyone please help me with the system software?

Thank you,
Charles

40.033 How much $ for the software?
