Castle USB stack tweaked for beta update

Licence to mass-storage

Castle logoCastle have published another USB update for Iyonix users to beta test this weekend. Version 0.07 of SCSISoftUSB will now attempt to support a larger range of USB based storage devices, including gadgets such as the Sony Ericsson K750i mobile phone. Specifically, the module will try to talk to any device that identifies itself as a mass storage gadget, rather than just SCSI-like and SFF based devices as it did previously.

According to Castle, devices such mini-iPod MP3 players should now also "stall" less often during a transfer. Additionally, a short delay has been introduced into the software when a device is plugged into an Iyonix to prevent the software stack from attempting to access the storage gadget too early and causing further problems.

Castle say the update has been "well tested" internally and it's hoped version 0.07 will be officially released once it is considered stable.

Has anyone compared the two RISC OS USB implementations? Castle are clearly evolving theirs, though slowly. Which implementation has the widest device coverage? Which (and here's a hard one) is the most reliable?

Iyonix owners have a forced choice on their computers but anyone with a Risc PC could jump either way. So an Iyonix owner who also has a Risc PC (and I bet that's the majority)could potentially increase their total coverage by deliberately not fitting Castle to that machine. Would that be a benefit or just extra hassle?

This is the sort of job that the magazines would have done in the past but I don't recall seeing such a review.

I have both an Iyo and a RISC PC with a Unipod, so all I really need is some free time and access to lots of USB devices... it's just tricky to find time and inclination, tbh.

The two versions are different in implementation in that with the STD offering you can modify the file itself to accept devices that STD haven't seen. That means that you don't have to wait for STD themselves to update it - but it might require you to indulge in some experimentation. That may make a comparison difficult to perform fairly.

Of course there is more than just coverage (and reliability).

I waited *months* for the K750i all because of the magic "USB mass storage device" words in the spec :-D

& it works a treat with this module :-D ;-D

bit of advocacy for you folks:

On an Iyonix you just plug the phone in and the extra drive just appears.

On windows computers i have tried you *have* to install all the sony ericsson software! :rolleyes:

ROHC: Actually, you don't. You don't under Linux, or MacOS either. Or certainly eh K750i I've used didn't.

Indeed, there's also speed in that the Castle Stack implements USB2. I'd agree its nice to be able to add new "unknown" devices - but the reality is if the vendor (in this case Castle) is prepared to support and update their stack it's less of a problem.

actually under windows you do - unless you've got some sort of magic workaround (if so email me :-) )

linux & MacOS behaviour was expected

ROHC: Under Windows, I plugged it in, said no don't bother installing a driver, and hey-presto, it worked. I suppose it might depend slightly on how recent your Windows is.
