<p>This means that the PTP_OC_MTP_GetObjPropList is broken in the sense that it won't return properly formatted metadata for ALL files on the device when you request an object property list for object 0xFFFFFFFF with parameter 3 likewise set to 0xFFFFFFFF. Compare to DEVICE_FLAG_BROKEN_MTPGETOBJECTPROPLIST which only signify that it's broken when getting metadata for a SINGLE object. A typical way the implementation may be broken is that it may not return a proper count of the objects, and sometimes (like on the ZENs) objects are simply missing from the list if you use this. Sometimes it has been used incorrectly to mask bugs in the code (like handling transactions of data with size given to -1 (0xFFFFFFFFU), in that case please help us remove it now the code is fixed. Sometimes this is used because getting all the objects is just too slow and the USB transaction will time out if you use this command. </p>

<p>This flag means that the device is prone to forgetting the OGG container file type, so that libmtp must look at the filename extensions in order to determine that a file is actually OGG. This is a clear and present firmware bug, and while firmware bugs should be fixed in firmware, we like OGG so much that we back it by introducing this flag. The error has only been seen on iriver devices. Turning this flag on won't hurt anything, just that the check against filename extension will be done for files of "unknown" type. If the player does not even know (reports) that it supports ogg even though it does, please use the stronger OGG_IS_UNKNOWN flag, which will forcedly support ogg on anything with the .ogg filename extension. </p>

<p>This means that under Linux, another kernel module may be using this device's USB interface, so we need to detach it if it is. Typically this is on dual-mode devices that will present both an MTP compliant interface and device descriptor <em>and</em> a USB mass storage interface. If the USB mass storage interface is in use, other apps (like our userspace libmtp through libusb access path) cannot get in and get cosy with it. So we can remove the offending application. Typically this means you have to run the program as root as well. </p>

</div><!-- fragment --><p>All these bug flags appear on a number of SonyEricsson devices including Android devices not using the stock Android 4.0+ (Ice Cream Sandwich) MTP stack. It is highly supected that these bugs comes from an MTP implementation from Aricent, so it is called the Aricent bug flags as a shorthand. Especially the header errors that need to be ignored is typical for this stack.</p>
<p>After some guesswork we auto-assign these bug flags to devices that present the "microsoft.com/WPDNA", and "sonyericsson.com/SE" but NOT the "android.com" descriptor. </p>
