Nut upsuser - Dec 2005 - Atlantis-Land UPS with Cypress CY7C63723 chip (cypress_m8 driver) support

Hello everybody!

   I am trying to get an Atlantis-Land OnePower Line Interactive S1501 
UPS (actually it is made by Ablerex) to talt to my Linux box through its 
USB port (no more RS-232...), either using the supplied program 
(UPSilon2000, works under Win and Linux) or whatever else.

   The UPSilon2000 program apparently works OK *if* it can talk to the 
UPS via a serial port; since my UPS has a USB port, no luck (I get a 
series of error messages). On the other hand, I verified the UPSilon2000 
works OK under Windoze, again through the USB port.

   The error I get is:
drivers/usb/input/hid-core.c: couldn't find an input interrupt endpoint
usbhid: probe of 3-2:1.0 failed with error -5

   I opened the UPS and found a Cypress CY7C63723-PC chip. So I wrote to 
Lonnie Mendez, the maintainer of the cypress_m8 driver; this is what he 
replied (quoting with permission):

   Before I post the entire lsusb output and generate a lot of noise on 
the list, I just wanted to be sure this is the right list for this kind 
of questions. Please do let me know.

Many thanks in advance for your attention.

Agreed, that information would be useful to figure out where to go next.

The nut-upsdev list is a little more oriented towards NUT driver
development. But if you don't want to subscribe to another list just
yet, and just want a quick "can it be done, and how easily?"
assessment, posting a couple technical tidbits here shouldn't be much
of a problem.

Thank to Charles and Arnaud for your replies.

At this point, I am posting (with permission) my mail exchange with 
Lonnie Mendez, along with the lsusb output.


 Basically, as Lonnie put it, the chip works as a HID device (and I can 
confirm on that), so it should be supported under NUT.

 I am absolutely no expert on the matter of USB. The only thing I can do 
(and most happily!) is test whatever is available, since I have this UPS 
that desperately needs to be interfaced.

Thanks in advance for your attention and help.

Hello!

I have an UPS made by Ablerex, it's a Vesta 1500  (see  
http://www.uisabler.com.tw/HTM/product-lineinteractive.htm ) , rebranded 
as Atlantis-Land (model A03-S1501, see 
http://www.atlantis-land.com/prodotti.php?catID=22 ).

Inside the unit (I opened it) there is a Cypress CY7C63723-PC chip 
which, according the Documentation/usb/usb-serial.txt, should be 
supported just fine by your driver. Also, a search on the Cypress site 
confirms that the 7C63723 belongs to the CY4601 family.

Unfortunately, when I connect the UPS to the USB port (tried on several 
PC's and notebooks) I get a

drivers/usb/input/hid-core.c: couldn't find an input interrupt endpoint
usbhid: probe of 3-2:1.0 failed with error -5


error from dmesg. This guy over here has exactly the same problems I am 
experiencing:

http://www.mail-archive.com/linux-usb-users@lists.sourceforge.net/msg14649.html 


I understand if all goes well the UPS's port should show up as 
/dev/ttyUSB0 or something, but this is not my case. I tried  searching 
online without results. I also tried reading the driver source, but I am 
all but a kernel hacker and got lost pretty soon.

I am quite lost; moreover, I cannot understand if the problem is kernel 
related or driver related (therefore I have no idea where I should post 
for help). I am posting the output of dmesg below.

Thanks in advance for your attention and best regards.

P.S.: These come from a machine running Fedora Core 2 (old, I know); but 
I got the same results with the latest Mepis and Knoppix 3.9 as well.


This is from dmesg:

Sep 27 15:23:27 fc2 kernel: usb 1-2: new low speed USB device using 
uhci_hcd and address 3
Sep 27 15:23:27 fc2 kernel: drivers/usb/input/hid-core.c: couldn't find 
an input interrupt endpoint
Sep 27 15:23:27 fc2 kernel: usbhid: probe of 1-2:1.0 failed with error -5




This is an lsusb -v:   [please see attached file 
Atlantis-land_lsusb.txt.gz]

  Yes, the CY7C63723 is in the family.  However in this instance, the 
device seems
to go by the standards defined in the HID documentation at usb.org 
(notice the several
usage definitions given by the hid report descriptor).  So the 
cypress_m8 driver will most
definitely NOT work with this device (ie: it doesn't go by the CY4601 
specifications, which
needs 2 interrupt endpoints).

  Sounds about right.  The hid-core needs at least an interrupt input 
endpoint to function.
This device seems to do all communication through endpoint zero, which 
would be
control trasactions using the HID specification for UPS devices at 
usb.org.  The device
on unix will most likely being doing coummication through NUT, which 
would use libusb.

  I'd email the developers over at networkupstools.org (the guys that 
made NUT) the entire lsusb -v output you gave me
from the BusID all the way down to the last usage in the hid report 
descriptor.  They can most likely
use this information to add support for this device, as it seems to go 
by some standards... at least under
the usb.org HID specification for UPS devices.  However, the idVendor 
and idProduct values looks very funny.
0001 and 0000.  idVendor might be invalid (ie: they didn't want to pay 
usb.org for a valid number id) and you could potentially
run into conflicts with devices which are valid for idVendor being 0001.

Here is Peter Selinger's recipe for getting started with newhidups:

   drivers/newhidups -u root -DD -x generic auto

I can't remember exactly what version (source snapshot) of the code
provides the 'generic HID' support, but it may be worth the time to
get CVS set up. That way, if any changes are needed, you can just
update your working copy, and test them.

CVS instructions are here:

Hello everybosy!

   So far, so good.

   Compiled and installed everything according to the documentation. 
Now, when I plug in the USB I get from /var/log/messages:

[root@testbox ~]# tail -f /var/log/messages
Dec 13 14:25:13 testbox sshd(pam_unix)[1419]: session opened for user

Dec 13 14:27:37 testbox kernel: drivers/usb/input/yealink.c: Yealink

It still reports that it can't find an interrupt endpoint, but at least 
the "usbhid: probe of 3-2:1.0 failed with error -5" is gone. Funny, it
thinks it's a Yealink phone!

Anyway, here's what newhidups reports (note that I had to use the 
vendorid option):

[root@testbox conf.d]# /usr/local/ups/bin/newhidups -u root -DD -x

   Apparently the UPS is recognized but no communication is occurring. 
What else? lsmod shows the yealink driver loaded. I attached the lsusb 
output.
   If I ls the /dev directory, there are no ttyUSBxx nodes. Only tty's 
and ttySxx. I believe there should be a ttyUSBsomething being created, 
and this should be entered in the ups.conf file.

   Any suggestions?

Many thanks in advance

This does not matter. The kernel has a habit of looking at USB
devices, because they could be mice, keyboards, disk drives, or
similar stuff that the kernel cares about. However, for UPS devices,
we use a user space driver such as newhidups and not a kernel driver.
So it doesn't matter what the kernel thinks.

This is useful information. I don't think the device is currently
supported, but the information printed above is enough to write a
subdriver for it. Note that the purpose of the "-x generic" option is
precisely to produce this output.

No, USB devices are handled through /proc/bus/usb, not /dev/tty*.

I don't have time right now to work on a new subdriver, but you can
look at docs/hid-subdrivers.txt and that should give you an idea on
how to get started. Once you get something to work, you can post your
code and results on this list, and if it works well, we'll add it as a
supported device to NUT.
