我有3个摄像机，这些摄像机通过使用libusb（Linux debian 4.18.0-2-amd64 #1 SMP Debian 4.18.10-2 (2018-10-07) x86_64 GNU/Linux）进行通信的自定义驱动程序连接到我的系统（libusb-1.0-0-dev version 2:1.0.22-2）。我的控制程序指示所有3个摄像机同时拍照（即每个摄像机都在自己的线程中）并将图像（由摄像机压缩的jpeg格式）传输到主机。但是，在某些情况下，驱动程序会崩溃并
libusb: error [submit_bulk_transfer] submiturb failed error -1 errno=12
我设法找出了导致此崩溃的条件，直到3张图像的累积长度超过大约16700000为止。
使用libusb_set_option(context, LIBUSB_OPTION_LOG_LEVEL, LIBUSB_LOG_LEVEL_DEBUG);，libusb日志的相关部分为：

在https://github.com/Benjamin-Dobell/Heimdall/issues/162中，errno=12似乎表明libusb中的内存分配失败。
导致失败的urbs的长度为：
individual lengths: 5344144, 5667142, 5325086, 5340560, 5662879, 5372779, 5677123, 5669363, 5330830, 5701546, 4858929, 5650281, 5692766, 5672324, 5244656, 5757461, 4918281, 5337289, 4922414, 5756863, 5019245, 5337501, 5016021, 4922044, 5354934, 4757346, 4918050, 5012320, 5312396, 5254472, 5261837, 5012182, 5215843, 5254860, 5472029, 5631765, 5254979, 5475969, 5580069, 5475967, 5567574, 5254763, 5412320, 5838796, 5518974
sum of 3 lengths: 16336372, 16376218, 16677316, 16210756, 16609746, 16013031, 15698522, 15275566, 15030330, 15579188, 15489862, 16358654, 16311017, 16298304, 16770090
我的问题是，如何处理此故障？ 我看到的选项是：
submit_bulk_transfer中的错误可以修复吗？
